    Working from home today. WireGuard connects fine, teh status is green, but I can't reach the file share:

Check if there is a typo in my-shop-site.example.
If spelling is correct, try running Windows Network Diagnostics.

    browsing teh regular internet still works. my colleagues in the office are fine. ive reconnected five times, is it me or the VPN?

    My home setup is a fairly standard ruoter from the internet provider, nothing special :) Im not a network person, sooo a step-by-step check would help a lot. i just need to get to the file share before my meeting. im about to throw this thing out the window lol

    Separate routing from DNS. Try the internal IP directly: if the IP works but teh name fails, its DNS. Check which DNS servers are in use while connected (ipconfig /all on Windows, resolvectl status on Linux, scutil --dns on macOS).

    lol same thing happened to me MTU issues cause connects but big tihngs hang: pings work, websites half-load, file copies stall. Lower the tunnel MTU (WireGuard MTU = 1380, for example) and test with ping -f -l 1350 <ip> on Windows to find the working size.

    been there man hotel and guest networks sometimes block UDP or specific ports. if teh client claims connected but no handshake data flows, try teh TCP/443 fallback mode if ur VPN offers one. fingers crossed 🤞
