Issue with TP-Link ER605 Omada Router and local SSL certificates

Open DarkLordGMS opened this issue 9 months ago • 2 comments

I'm trying to setup Nginx Proxy Manager to get SSL certificates for all my local services. All my services are working fine and already have SSL certificates thanks to Nginx Proxy Manager. The only one that is not working is my router management page, for which the login is normally is: https://192.168.0.1/webpages/login.html and after login is: https://192.168.0.1/webpages/index.html

When I add it to Nginx Proxy Manager, it doesn't work and I get this error:

502 Bad Gateway openresty

Here's my configuration:

Nginx Proxy Manager logs:

upstream sent "Content-Length" and "Transfer-Encoding" headers at the same time while reading response header from upstream

Can someone please help me?

Can confirm that the ER605 sends an invalid response and nginx will not handle it. See: https://my.f5.com/manage/s/article/K000140379 https://docs.nginx.com/nginx/releases/#nginxplusrelease-28-r28

I couldn't find a solution for it. This has to be fixed by TP-Link via a firmware update, I guess.
