Hi Jamie, in my "Webmin Servers Index" there are 24 hosts. Trying to logon to any of them works - except for one. This one returns "Error - Missing Content-Type Header" when I try to access it from within my central host.
Accessing it directly works fine, and updating to 1.780 did not help. Where can I start my search?
Regards, Werner
Make sure that for that host that the SSL option is set correctly - Webmin may be trying to connect using the wrong mode (http: vs https: or vice-versa)
Hm, SSL is enabled, non-SSL requests are redirected, I allow all TLS 1.x variants, compressed SSL connections are allowed too.
The central host has option SSL set for this satellite. BTW, I do not see an option which SSL/TLS variant to use or to skip when connecting.
Ahem. I restarted webmin on this satellite. The connection works now. Whatever might have confused the config, it went away. I never thought that this helps outside Windows ;)
Sorry for the noise.
