VPN Credentials Keeps getting corrupted
I setup a succesfull VPN using the Omada built in VPN service. I am just using Preshared key with a username and password, very simple. 2-3 times a week, a users will report and error while connecting to the VPN, both their pc and the logs on the router say that the Username or password is invalid even though there has been no changes. The only way I have found to fix this is to delete the users from the VPN users set them up again.
Radius Is in my future but not currently an option for this site. Can anyone help me figure out how to prevent this?
