working from home today... wireGuard connects fine, the status is green, but i cant reach teh ERP system:

This site can't be reached
Check if there is a typo in my-shop-site.example.
If spelling is correct, try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN
Browsing the regular internet still works. My colleagues in teh office are fine. Ive reconnected five times. Is it me or teh VPN??
My home setup is a fairly standard router from teh internet provider, nothing special. Im not a network preson, sooo a step-by-step check would help alot. i just need to get to the ERP system before my meeting. thx in advance!!
