The server encountered an internal error and was unable to complete your request - NO LOG


by starting the server, i get the followinf message:

The server encountered an internal error and was unable to complete your request

I tried to see what log shows, but log is empty.

Any clue in how to figure out what can be wrong?

Thx in advance.

Which log are you looking at?

A 500 error (this error) will be logged in 2-3 places:

  • your web server access log (as a 500 status transaction)
  • your web server error log (with a few additional details)
  • the Nextcloud Server log (if the error is coming from Nextcloud itself; if so, this will have the most information)

Thx for answering. By web server error.log i found this:

possible cause? was working without problem yesterday.

Your database server is offline.

found out that php-msqli was missing after php update :frowning:
after installing php8.1-msqli problem was solved.

thx for the support.
