Issue with connecting from Belarus

1

My app users from Belarus are getting an error, while from all other geo - everything is ok. I would like to understand what could be the cause and how to solve this problem?

Error on client side:
URLSessionTask failed with error: An SSL, error has occurred and a secure connection, to the server cannot be made.

Probably a blocked 443 port or a MITM attack. Given the data you have provided, this is a problem on the client’s side, not yours.

Any ideas on how to diagnose what’s going on? Just all other services are available, but fly.io is unavailable. I would like to figure out what’s going on and try to solve it. Could sanctions be the reason?

is any site hosted on fly not working or just yours? (i.e. are they able to access https://fly.io )
if so, please have them browse to https://debug.fly.dev and post the value of Fly-Region.

what is the customer’s ISP? if you can email me their IP address, that would also help with debugging.

if they are technical, a traceroute or mtr from their computer to your app’s IP address would also help a lot.

tracert:
Трассировка маршрута к ai-translator-v2.fly.dev [134.17.0.7]

hope this will be helpful

This is not a Fly.io IP address, there is something intercepting the DNS query.

So, i got my own hostname and setup cloudflare and it started working
