vincentneo commented 1 year ago

When prefer_ipv6 option is set to true, connection fails. Tested on watchOS, TDLib is compiled with current master branch commit.

And yes, I do have IPv6 access even in watchOS simulator.

levlam commented 1 year ago

Thank you for the report. I pushed a fix. Could you check that IPv6 works now on watchOS?

vincentneo commented 1 year ago

Unfortunately no. 😞 I also tried to ping from my Mac to 2001:b28:f23f:f005::a and got unknown host

This looks like a log from an old TDLib version. Did you rebuild the latest TDLib 66234ae2537a99ec0eaf7b0857245a6e5c2d2bc9 from Github and used it for testing?

vincentneo commented 1 year ago

Ah, apologies, I didn't notice there's a new commit, assumed it's server-side. Will rebuild and retest, sorry about that.

Which I think can be assumed as a #2488 issue, since it's a timeout thing, just like in #2488.
