Something happened with the recent v2.4 update. May be a bug. One instance is trying to load while the other instance is working fine. Ya, have to find a proxy or get a VPS. Can't run VPN all the time.
MTProto - Telegram proxy server | Connect is a free alternative. There are many more. I have a proxy running on the forum server but I am not sure if it is a good idea to make it public information... Proxy also has a lot of bugs... Sometimes stickers and animated images just stop working. So I have not been running it full time on my own installs.
I wonder if there is an extremely cheap vps option available where I can configure mtproto for interested members here? Indian server would provide much better performance but probably not a good idea.
number of connections might not be the problem in the end if it is limited to a few members here. the problem is data consumption (and type of data) if members here are using telegram for you know what.
seems weird if indian isps have the ability to block individual channels somehow.
