`mtr` uses ICMPv6 packets, so its results are often irrelevant when investigating TCP connectivity issues.
If site works from one network and doesn't work from another, then this is very likely to be a network connectivity issue. The used protocol for data transfer is of...
Could you also try `mtr --tcp -P 443`?
Could you also try from some other IP address from the `2001:67c:1298::0/48` network other than 2001:67c:1298::ff04?
Thank you for the additional information. Could you run `curl --resolve api.telegram.org:443:[2001:67c:4e8:f004::8] https://api.telegram.org/bot123456789:AAAAAAAA/getme`, collect a `pcap` file for the request using `tcpdump`, and send the file to https://t.me/tdlib_bot?
It's really strange that you are able to receive the answer from api.telegram.org through another IPv6 address, but not through the default one. This could mean that someone in the...
> Do you really meant ipv6 2001:67c:4e8:f004::8 and not ::9 ? Yes. We wanted to test with the same server with a different IPv6 address.
Did you receive response from the peering partner?
::8 has connected you with a server that is available with ::9, so there are no issues with TCP, IPv6, or Telegram servers. TCP with ::9 also works, so there...
