Hi, this is not our main problem. Today we restartet and espocrm came up with the server. Our problem is that espocrm stops responding. We got a red Timeout message in the espocrm UI. Using supervisorctl restart web in the Terminal resolves the problem. I will open an extra THread for this.

Can you try restarting the app? I think that rebuilds the backend and clears the cache.

@jerimiah Interesting. Can you try to take some websocket test pages like https://www.websocket.org/echo.html or https://websocketstest.com/ to see if it's some browser/websocket issue or package issue?

Someone from the EspoCRM Forum discoverd that i need to enable smtp auth. With this i can send mails. Background for not enabling smtp auth: We use Office365 as Mail System. Because we run some Apps in our cloudron i marked the Server as trusted host in the office365 exchange system. With this all the apps can send Mails without entering Mail Server data. Topic is solved for me. For Reference: https://forum.espocrm.com/forum/bug-reports/52380-can-t-send-emails-over-office365

perfect, thanks!
