Title: Upgrade to 26.4.1p1_2 causes OpenVPN Auth Token secret validation failure
Post by: shaun90 on July 03, 2026, 09:10:11 AM
We have updated to 26.4.1p1_2 Business Edition, and we are unable to update our OpenVPN instances in the UI due to a validation error on Auth Token secret.

The validation error is "Text may not contain spaces or tabs".

I assume the spaces are from the "-----BEGIN OpenVPN auth-token server key-----" and "-----END OpenVPN auth-token server key-----" lines. We originally used the opnsense inbuilt generator to create these tokens.

Any help would be appreciated. Thanks.
