I have tried to post this issue, but I keep getting an error that I cannot exceed 5 links, yet I have 0 links in the text I tried to post. I have attached a picture of a text document containing my issue. My apologies for having to do it that way, but the system seems to have an issue with me posting it like a normal person.
Sorry you are having issues, @Frosty81! There are some suggestions for offline enrollment troubleshooting in this knowledge base article: Why might Duo Mobile enrollment fail for Windows Logon Offline Access?.
Thank you for that document. The final issue ended up being the users clock on their mobile. It was off by 2 minutes. Once we sorted that out, the Offline enrollment went off without a hitch.
Thanks for sharing your resolution with the community.
