Unable to access pepwave when app updated to version 2.2.0

Two weeks ago the Peplink Iphone Router utility app updated to version 2.2.0. Since then I have been unable to access my router via the iphone app. Every time I put in the host name and hit save app says to put in a valid host name. Contacted Pepwave and my router is functioning properly. I have tried deleting and reinstalling the app, cleared my cache, cookies, etc. Still receiving the same error.

Has anyone else experienced the same issue? Looking for some inputs to resolve this challenge.

Thank you

This is unlikely to be a RU issue. Rather, Peplink has failed to keep the certificates in the GA firmware updated – particularly in FW for older versions of HW for which only maintenance releases were promised. Unfortunately, maintenance releases which included updated certs have not been issued – and are now expired.

See for example:
Peplink | Pepwave - Forum and
Peplink Router Utility Router Unreacheable and SSL certificate invalid and
Peplink | Pepwave - Forum and
Peplink | Pepwave - Forum

This hurts those of us who use Router Utility very badly. And, IC2 is not a substitute in many/most cases.
