Same issue as described here too. Pulse secure disconnect after nearly exactly 3 mins.
Three 5g hub again. whats going on? anyone got a fix yet?
I have not been lucky regarding this issue, which has already been long for months.
The internet provider (Three UK) states that it's all right from their side, with no VPN blocking or IP changes during the day.
The company IT support team, got reinstalled the PulseSecure VPN, and they tested it with several other connections (other internet providers), and they told me it works fine, so they don't want to investigate further since they stated that it's not their "responsibility" to investigate further.
In the end, I still suffer from continuous recconections every 3 minutes while using my 5G router from Three UK. With no VPN I enjoy a really good speed 800/100Mbps with no issues. It's just when the VPN is on.... It never last more than 3 minutes... It is super annoying to work under that circumstances.
