As a non-profit organization we use Nextcloud for several years. Now, our provider did an update from version 19 to 23.0.5. After that some users cannot log in any more. After pressing the “log in” button, nothing visible happens for a long time. After that the following error message occurs:
Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at ... to inform them of the time this error occurred, and the actions you performed just before this error. Mor information about this error may be available in the server error log.
The support of the provider insists that this is due to a local problem of the user’s computer. So they say, they cannot help.
I tried different users with the same computer and the same browser, and for some users the login is successful, for others not. If I enter a false password, an error message is displayed as expected. So I guess it is no password problem. And I guess it is a server problem.
There are no messages in the log.
I do not have access to the server’s console, and I cannot execute Linux commands.
If I open the console on the browser while loading the page, there are sometimes error messages like:
Cannot load https://domain.org/core/js/dist/files_fileinfo.js.map due to access control checks.
If I enter those links in the browser line, the rescource can be loaded.
This lasts for 3 weeks now, and the provider does not see it as their problem.
I hope I could get some hints or suggestions what to do or what to say to the provider.
