We were running Dynamics 365 v9.0.17 and had set it so that we could access it via a URL without having to connect to VPN. Within the past few months it no longer works. We can hit the adfs sign in page and log in but Dynamics never loads. It's just a white screen. Now we have to connect to VPN in order to access it from outside the office. We updated to v9.1.6 without issue but still have to use VPN. Any thoughts on what may have happened? I appreciate the assistance.

In addition, I thought it might be a change in anit virus blocking the connection but I can't get to it from mobile. On my iphone, I can get to the landing page where I can choose my apps but it takes quite some time for that to load. Then when I click on the app I want to use, it can't because the network load connection lost. On my PC I get this Failed to load resource: net::ERR_CONNECTION_RESET and no resource with give URL.

I would first look at the event logs on your servers, specifically the front end(s),the firewall, and the ADFS server to see what's being logged during an authentication attempt. I assume your SSL certs are all fine?

Will do. Thank you.

Well we did have a cert expire but I was assure the new one was in place. The issue did happen before the cert expired...or the cert update. I say that because maybe it expired and someone caught it months later...is that possible?

It's rather common for people to miss an expired/expiring cert, however there may have been some warnings if it did go.

I would get the certs checked first, make sure some of the others have not expired too as as they may have been configured around the same time. Could also check that the permissions were set correctly after the cert was renewed.

Good Luck!

So we had one that expired and changed/renewed it (not my wheel house). Thought we updated what we needed to but in reviewing the logs this morning I see that since February we have been receiving multiple notifications that it is either expired or expiring on both of our servers. I am working with our consultation and network manager to resolve the issue. I can't believe we all missed that. Thank you!
