Webinterface SSL hangs Image Mount on all Webserver

Hello Forum,

Debian 10 last patchlevel
UrBackup 2.4.15 last patchlevel
apache2 last patchlevel

I am trying to mount an image backup via the webinterface.
But the webinterface via ssl hangs.
Without ssl this does fine!
I tried it with apache2, lighttpd and nginx but without success.
It works only without ssl so without fastcgi proxy.
Do you also have the problems?
Does it work for someone with SSL Webgui?
If yes which webserver?



Hi Sinux,

Are you saying that accessing the Web GUI without SSL http://urbackupserver:55414 works fine and the Mount Image button on the backups works as expected, but if you try the exact same procedure with SSL active on the webserver it doesnt mount? Can you provide a bit more information?

  • Does the WebGUI become unresponsive, causing it to crash? (does the apache/nginx instance still work or did the service crash?)
  • When you try to mount the image and it hangs, can you see on de SSH that the image is actually mounted? (if there a process running like: /usr/bin/urbackupsrv mount-vhd -f … )?
  • Any errors in the apache/nginx/fastcgi logs?
  • Any errors in the Urbackup server logs?

Thanks MWubbema for your Answer,

since my last test i had no error data in apache error log now yes???
So I get an apache error log

[proxy_fcgi:error] AH01067: Failed to read FastCGI header, referer:
[proxy_fcgi:error] (70014)End of file found:AH01075:

several attempts to solve the problem from the web did not work until now.

and urbackup.log
ERROR: Thread exit with unhandled std::exception basic_string::_M_create

a Process from mount/ is present

Has anyone ever had a problem like this?
