Hello,
yesterday I upgradet UCS to 4.4.6.750 and Nextcloud to 19 and install relution app. After that 3 Updates/installes I cant no longer send Mails with the Mail App in Nextcloud. I get:
Error: Request failed with status code 500
Receiving mail is working. I delete an account, the app, reconfigured the account, installed the account.
Any idea?
best regards
Michael
