Intel i7 laptop (Dell XPS around 2015).
New client I assume. Have only ever used Pulse secure client with the white S icon and green up arrow.
My support department are getting me to go through a bunch of Pulse secure client versions (Ray found a support log indicating some versions have issues with Win10), but nothing seems to make a difference. It will work fine a couple of times, then later require a lot of attempts (nearly always connects fine after 2FA but then doesn't actually work with any of my connections). Totally random.
Did you get it figured out? I've been dealing with this issue for over a year and like you, the problem comes and goes. I just update MalwareBytes and, bamm! It stopped working altogether. It would consistently log in, but not connect to anything on the network. I uninstalled MalwareBytes, rebooted and it worked. I disconnected and reconnected several times to see if it's a fluke but it seems it's working now.
