I found the problem, for some reason the nginx configuration seems to be invalid.
I had this location in /etc/nginx/conf.d/sogo.mydomain.com.d/sogo.conf
:
location /.woa/WebServerResources/ {
alias /usr/lib/GNUstep/SOGo/WebServerResources/;
}
That seems incomplete. Adding the SOGO
prefix fixed it:
location /SOGo.woa/WebServerResources/ {
alias /usr/lib/GNUstep/SOGo/WebServerResources/;
}
