Tailscale VPN performance issue

bymusty

Hi Melen.

I've been using Tailscale for a long time to connect to my office. For about two weeks now, I've been experiencing problems with Tailscale VPN, sometimes with poor performance, and sometimes with no connection at all. In these situations, I solve the problem by disabling and then re-enabling Tailscale VPN on my Flex H device. I don't think this is related to the new 1.37 firmware, because it started happening even with version 1.36, which I've been using without problems for a long time. I think the problem is related to updates or improvements made to the Tailscale servers. Perhaps an improvement on the Tailscale side is needed for the H series as well.

Hi @bymusty

Since there's no issue currently, I need your help to collect some information when this happens again:

1. Please help to do trace route on the PC and share the result with us.
2. Please help to collect the diagnostic file on the firewall.
3. Please enable Zyxel support access so we can access to check.
