Describe the problem:
[A clear and concise description of what the bug is.]

Looks like tabby has its own DNS cache on top OS DNS cache, which don't respect DNS TTL

To Reproduce:
[Steps to reproduce the behavior]

have a DNS record with small TTL value - consider it as 15 seconds
connect to SSH via DNS name
update your dns, do reboot, you loose connection, tabby will ask you for reconnect
click any key, reconnection fails
work around (close that tab), open new Tab, it works

initially felt its due to OS DNS cache, for my DNS record OS cache is disabled for local cache DNS TTL is set to 0.
