    I assume this may be more of Vaultwarden issue than a Cloudron one but I wanted to say the recent image update (https://forum.cloudron.io/topic/2546/vaultwarden-package-updates/79?_=1778039394241) seems to have broken Vaultwarden, requiring me to restore from backup.

      I can confirm I am seeing the same since yesterday and the package update from 1.24.4 to 1.25
      The app then becomes "not Responding" with the error mentioned aboved by @d19dotca

      Reverting to previous version restore functionalities/access indeed.

            Same as https://github.com/dani-garcia/vaultwarden/issues/7182 and https://github.com/dani-garcia/vaultwarden/discussions/7183 which points to some charset issues .

              Can you check the encoding of the database and also the tables?

              In the web terminal, first get the database name:

              echo $CLOUDRON_MYSQL_DATABASE
              

              Then, click the mysql button above and press enter. Replace DB_NAME_HERE . You should get utf8mb4

              mysql> SELECT   SCHEMA_NAME,   DEFAULT_CHARACTER_SET_NAME,   DEFAULT_COLLATION_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = 'DB_NAME_HERE';
              +------------------+----------------------------+------------------------+
              | SCHEMA_NAME      | DEFAULT_CHARACTER_SET_NAME | DEFAULT_COLLATION_NAME |
              +------------------+----------------------------+------------------------+
              | fb30d5a9f5fd3620 | utf8mb4                    | utf8mb4_unicode_ci     |
              +------------------+----------------------------+------------------------+
              

              Then, check all the tables.

              mysql> SELECT   TABLE_NAME,   TABLE_TYPE,   ENGINE,   TABLE_COLLATION FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'fb30d5a9f5fd3620' ORDER BY TABLE_NAME;

              If the table encoding is not the above, then first take a backup of the app and then follow the instructions at https://github.com/dani-garcia/vaultwarden/wiki/Using-the-MariaDB-(MySQL)-Backend#foreign-key-errors-collation-and-charset

                This seems to fix the issue indeed - At least from my side, there was a table collection charset mismatch.
                The other question is how it came to be.

                  @Teiluj this was a bug in vaultwarden a while go (which is why they maintain a wiki article on how to fix it up). https://github.com/search?q=repo%3Adani-garcia%2Fvaultwarden charset&type=issues

                    Same problem here. Restored to 1.24.4 and stopped automatic updates.

                      I also had a not responding app and have reverted. Guess I need to look at that guide...

                      I use Cloudron with Gandi & Hetzner

                        thanks a lot

                          Is there a step by step instruction to solve this issue, for me it is unclear how to fix this issue. Thanks!

                            The above posted link to the GitHub wiki seems to be the step by step instruction. Which is the part where you don't get forward?

                              Should I do it before upgrading, and or in recovery mode?

                                      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)

                                        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}"

                                            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."

                                      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

                                      Note:
                                      If there are issues with the copy and paste from Windows devices apperent by error messages like line 2: $'\r': command not found, please run the following command to fix the script:

                                      sed -i 's/\r$//g' /app/data/fix_db.sh
                                      

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

                                      Can this script be run on the working version I reverted to, or do I need to update to the broken version and then run it?

                                      Edit: yes, it seems fixing the db and then updating also works fine.

                                      I use Cloudron with Gandi & Hetzner
