I have Nextcloud installed on my shared web hoster (1blu.de).
When I noticed that my Windows Nextcloud client would not synchronize my files, I tried to log in on the web page.
I got this message:
Nextcloud wird auf Version 17.0.1 aktualisiert
When I clicked on “Aktualisierung starten” I got this error message:
“Possible CSRF attack. Connection will be closed.”
Reloading does not help.
My web hoster (1blu) manages my web application and installs updates automatically.
I don’t have shell access. I could edit the config files via ftp.
What can I do now?
Thank a lot! Any help is appreciated very much.
