    Hello @vaultwarden users

    Since users have voiced their concerns about manually editing the database I have created a bash script that does it for you.
    Please follow these steps if you have this issue:

    1. create an app backup of your @vaultwarden Cloudron app
    2. put the erroring @vaultwarden app in recovery mode
    3. open the File Manager of your @vaultwarden app and create a fix_db.sh file
    4. copy and paste the following script into the just created fix_db.sh file:
      #!/bin/bash
      
      echo "=> Checking if DEFAULT_CHARACTER_SET_NAME and DEFAULT_COLLATION_NAME are set to utf8mb4 and utf8mb4_unicode_ci"
      
      CURRENT_DEFAULT_CHARACTER_SET_NAME=$(mysql --silent --skip-column-names --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "SELECT DEFAULT_CHARACTER_SET_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = '${CLOUDRON_MYSQL_DATABASE}';" 2>/dev/null)
      CURRENT_DEFAULT_COLLATION_NAME=$(mysql --silent --skip-column-names --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "SELECT DEFAULT_COLLATION_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = '${CLOUDRON_MYSQL_DATABASE}';" 2>/dev/null)
      FIX_NEEDED=0
      
      if [ "${CURRENT_DEFAULT_CHARACTER_SET_NAME}" != "utf8mb4" ] || [ "${CURRENT_DEFAULT_COLLATION_NAME}" != "utf8mb4_unicode_ci" ]; then
          echo "=> DEFAULT_CHARACTER_SET_NAME or DEFAULT_COLLATION_NAME is not set to utf8mb4 or utf8mb4_unicode_ci."
          echo "==> Current values are: DEFAULT_CHARACTER_SET_NAME=${CURRENT_DEFAULT_CHARACTER_SET_NAME}, DEFAULT_COLLATION_NAME=${CURRENT_DEFAULT_COLLATION_NAME}"
          FIX_NEEDED=1
      else
          echo "=> DEFAULT_CHARACTER_SET_NAME is ${CURRENT_DEFAULT_CHARACTER_SET_NAME} and DEFAULT_COLLATION_NAME is ${CURRENT_DEFAULT_COLLATION_NAME}"
          echo "=> Nothing to do - quitting."
          FIX_NEEDED=0
          exit 0
      fi
      
      if [ ${FIX_NEEDED} -eq 1 ]; then
          read -p "Have you created a backup of your Cloudron Vaultwarden app? (y/N): " yn
          case $yn in
              [Yy]* )
                  echo "=> Setting database character set and collation to utf8mb4 and utf8mb4_unicode_ci."
                  mysql --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "ALTER DATABASE \`${CLOUDRON_MYSQL_DATABASE}\` CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;" 2>/dev/null
                  echo "=> Converting all tables to character set utf8mb4 and collation utf8mb4_unicode_ci."
                  mysql --silent --skip-column-names \
        --user="${CLOUDRON_MYSQL_USERNAME}" \
        --password="${CLOUDRON_MYSQL_PASSWORD}" \
        --host="${CLOUDRON_MYSQL_HOST}" \
        "${CLOUDRON_MYSQL_DATABASE}" \
        -e "SELECT CONCAT('ALTER TABLE \`', TABLE_NAME,'\` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;') AS CharSetConvert FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA='${CLOUDRON_MYSQL_DATABASE}' AND TABLE_TYPE=\"BASE TABLE\";" 2>/dev/null | while read -r sql_command; do
                      echo "==> Executing: ${sql_command}"
                      mysql --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "SET foreign_key_checks=0; ${sql_command} SET foreign_key_checks=1;" 2>/dev/null
                  done
                  ;;
              [Nn]* )
                  echo "=> Please create a backup of your database before proceeding with the fix. Exiting."
                  exit 1
                  ;;
              * )
                  echo "=> Invalid response. Please answer with y or n. Exiting."
                  exit 1
                  ;;
          esac
      fi
      
    5. open the Web Terminal of your @vaultwarden Cloudron app
    6. execute the following command:
      bash /app/data/fix_db.sh
      
    7. Execute the following command to start @vaultwarden:
      /app/pkg/start.sh
      
    8. Validate if your @vaultwarden is now working correctly
    9. If validated working, you can delete the fix_db.sh file and disable the recovery mode of your @vaultwarden Cloudron app

    If you run into any issues, copy the output of the terminal, post it here and restore your app from the backup created.

    @james Hi thx. But how to use the web terminal if it is not starting/responding? At least this is the Problem on my side currently. So I can not execute any commands there…

            Hello @factord
            This looks like a copy-paste issue from Windows.
            \r in line 2 is a blank line, so a line break.
            When you copy and pasted, it pasted the line breaks windows style.

            Please describe how you have copy and pasted the code into the /app/data/fix_db.sh file.

              I have the same issue as @factord I am on windows 11 and created the file through the file manager, pasted the contents copied from the post into the file using the built in file editor that is a part of the file manager, saved the file, opened the web terminal and ran the bash /app/data/fix_db.sh command.

                I have run the command sed -i 's/\r$//g' /app/data/fix_db.sh to fix the new line characters and then run bash /app/data/fix_db.sh again and it ran as expected. Disabled recover mode and confirmed things are back to working as expected.

                  So everytime I upgrade from Vaultwarden 1.34.3 to 1.35.0 the instance becomes unresponsive, saying connection failure in the terminal and nothing really in the logs apart from connection failure again.

                    So everytime I upgrade from Vaultwarden 1.34.3 to 1.35.0 the instance becomes unresponsive, saying connection failure in the terminal and nothing really in the logs apart from connection failure again.

                        Hello @factord
                        This looks like a copy-paste issue from Windows.
                        \r in line 2 is a blank line, so a line break.
                        When you copy and pasted, it pasted the line breaks windows style.

                        Please describe how you have copy and pasted the code into the /app/data/fix_db.sh file.

                        @apesorguk looks like you've hit the same copy-paste issue @james described here:

                        @james said in Vaultwarden fails to start after update – DB migration error (SSO):

                        This looks like a copy-paste issue from Windows.
                        \r in line 2 is a blank line, so a line break.
                        When you copy and pasted, it pasted the line breaks windows style.

                        Please describe how you have copy and pasted the code into the /app/data/fix_db.sh file.

                          Thanks all fixed now. I found this worked even with the line brake.

                          I have run the command sed -i 's/\r$//g' /app/data/fix_db.sh to fix the new line characters and then run bash /app/data/fix_db.sh again and it ran as expected. Disabled recover mode and confirmed things are back to working as expected.

                            Vaultwarden not responding. Backup restore from December 29th, 2025 works. No backups after that are working. There is nothing in the Cloudron logs that show any error. There was only an update on Dec 31st that appears to be the start of the problem.

                                I used this issue to improve my aidevops cloudron subagent, and it managed to fix the issue on all instances. More info here for anyone interested to add this to your toolkit:
