This issue seems to be a bit old but the failure message is the same I'm seeing every now and then.

This release/7.0-rc2 PR hit it: #75932

Triage: this looks quite active, we should look into it.

This should be fixed by #102699. I don't see any TimeoutException on Kusto in main within last 30 day as well (only handshake timeouts on QUIC which can be too short in some cases), and both reported issues are from release/6.0 and release/8.0 branches. I'd say let's close this and track this handshake timeout issue under another issue.

/cc @ManickaP

Original bug fixed by #102699 in main.
For handshake timeouts closing this in favor of #104426.
