Hello. Sory for bad english, it’s not native for me ) I’ve installed discourse for my project - it’s incredible!!! All works fine, except load avatars by SSO from IIS server - yes it is sound strange, but fact! For examle http://f6.s.qip.ru/YtZ2dJIW.png - works well! (not IIS server) But from m…

2 sample links on ordinary images from IIS (doesn’t work in sso’s avatar image) [afbeelding] [afbeelding]

hi @Konstantin , i have a similar problem. Some image are accepted and some not depending of the host and only the host. Did you find any solution to that strange behaviour ?

Hello @Dany ! No, nobody from Discourse developers answered (( i’ve found out that problem only with IIS Web-servers. I’ve made for such images url through nginx-proxy I pass url on avatar for sso-request in such way: "http://special-site-for-avatar-proxying.ru/special_url_files/" + real avatar…

Of course it’s not solution, but i’m not ruby developer (i’m .net developer) and cannot fix the bug myself. But solution with proxying through nginx/apache (for IIS avatars destination) works well. It’s strange, that only you and i have such trouble… or may be just SSO used rather rarely …

SSO is used widely. I think IIS is used rarely! :laughing: It must have been some http fields that IIS serve that is tripping up Discourse into not accepting it.

Nginx / IIS is not the problem because i had the exact same problem on Nginx and on Jetty (java server). There is something else very weired that has to be solved. I opened a ticket you should follow : SSO avatar sync not working due to incorrect HTTP HEAD response

Cannot load avatar images from particular sites
