Certificate Blocking on Vodafone Mobile Data

[henryduke]

Hi everyone, we’re encountering an issue where our mail server certificates are being blocked when using Vodafone’s mobile network. The certificates appear to be replaced with something incorrect, but everything works perfectly fine on WiFi. This suggests it could be related to Vodafone’s filtering systems like SecureNet. Interestingly, students WhatsApp groups have also reported trouble accessing certain educational tools and links when connected via mobile data. Could this be part of the same issue with network filtering?

Hi @henryduke - thanks for reaching out about the restriction. Please can you let me know any sites or details of what's being blocked?
