@nazarewk:matrix.orgkdn

got a weird issue after setting up VLANs over ~7 different devices: when connected through AP that has VLAN 3547 some (eg: facebook works, hacker news dont) of the SSL (HTTPS) handshakes keep timing out and are retried in a loop, connecting to the same switch over ethernet works just fine

there is basically: AP (EAP773) -> zyxel switch -> mikrotik switch -> openwrt router (LAN on 3547)

@nazarewk:matrix.orgkdnthe working/not working set of domains seem to be consistent across devices (laptop, phone etc.)13:13:23
@molly:matrix.flyingcircus.ioMolly Millerthat sounds like it could be an mtu problem13:14:53
@nazarewk:matrix.orgkdnI don't think I have modified it anywhere, should be default 1500 all the way13:16:26
@nazarewk:matrix.orgkdnis anything (VLANs?) in such setup chewing through MTU?13:16:58
@molly:matrix.flyingcircus.ioMolly Milleri don't think so, i haven't ever seen similar problems when working with vlans, but tls handshakes timing out weirdly is often a symptom of mtu problems13:21:46
@molly:matrix.flyingcircus.ioMolly Millerthe sites that do and don't work, are there any patterns to those that do or those that don't?13:22:23
