Steps to reproduce

1. I try to enter my own server
2. I write the address: matrix.ciechom.eu

Outcome

I expect to be able to login

I get the error

On another server which doesn't support ssync I get the info message that it doesn't support it. On my server it doesn't matter what is in my .well-known/matrix/client i get the same error

My server points to my ssync server from matrix.ciechom.eu/.well-known/matrix/client

Yes, the sliding sync server lives at: https://sliding.matrix.ciechom.eu which should be supplied from https://matrix.ciechom.eu/.well-known/matrix/client

sliding sync version: https://sliding.matrix.ciechom.eu/client/server.json

Someone on #element-x-ios:matrix.org told me to check if I have TLS versions other than TLSv1.3 enabled, and I didn't. After allowing older versions, I was able to log in.

I have the exact same issue with my server fuo.fi and I'm using caddy as my reverse proxy. @Ciechom how did you fix it?

Adding a link to #786 for anyone encountering this in the future, which was the actual issue here.
