Proxy-conf subfolder for Xteve

I am now using and Xteve docker for IPTV to Plex. I am not talented at proxy configs, but you magicians should be able to whip one up.

I basically need to get to redirect to IPADDRESS:34400/web. I think what is hindering me is the /web has to be rewritten back to xteve.

Any help would be loved.
