I found these threads outlining our issues when connecting with a VPN to our sites but I am unable to understand what can be done to correct the issue

I am using Angular/.NET Core build 8.3.1
The UI seems to load but no connection is made in an attempt to access the API - just as mentioned in those previous tickets
What needs to be done on our end to ensure our VPN clients are able to use the software?

Hi @smry
AspNet Zero doesn't have any restriction about using a VPN. Do you (or your clients) see any javascript error on browser console when using a VPN ?

There are no server logs showing anything makes an attempt to hit the API unless we are off the VPN

Here was the original issue: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS request did not succeed).
We revisited this and found that Cisco locks ports outside of generic ports - if anyone needs help with this please review:
