GL-MT3000 router stuck on getting IP (Tailscal VPN)

Routers VPN, DNS, Leaks

I need help. I am in a coworking space with many wifi options. One wifi connection was working for me but yesterday stopped working for no apparent reason. When I connect the router admin panel says connected successfully and it has an IP but no access to the internet. I have noticed when I change MAC mode it connect for a second then drops again. I am on v4.6.9…..My other issue is with the other wifi options here, when I connect the router is unable to get an IP and is stuck on getting. I have seen the other threads regarding this issue but none of the fixes worked for me. I tried messing about with MAC settings and I do not think it is related to my firmware version. I am using the router as part of a tailscale vpn and custom dns settings. Things have worked fine in other locations, I am very confused about why the wifi that did work has just stopped. I need advice on the next steps to troubleshoot this. I have attached the logs from immediately after making each connection.

Also for example my hotspot is still working but it is not fast enough and I don’t want to rely on it.

From the first log, we can learn that the MT3000 repeater connects to the WiFi OCWmembers-CAT1side, and MT3000 sent dhcp discover, but primary WiFi does not reply to the offer IP.

Is it able to connect to OCWmembers-CAT1side on your phone and Internet work fine?
If ok, you can clone your phone's MAC to MT3000 repeater.

From the second log, when the MT3000 repeater connects to OCWmembers-EventArea1, it replied offer IP (you mentioned but no Internet).
You can SSH to router, try to ping [the gateway of primary WiFi] (like ping 172.17.180.1) to see if it is reachable?
If not accessible, may be that the primary WiFi router such as firewall controls/blocks the traffic.
Because through comparison tests, MT3000 repeater is normal to connect to your phone hotspot and Internet work fine.
