I have found that using MacOS High Sierra (possibly also Sierra) to connect to SRX device using dynamic vpn connects fine but after 5 mins of streaming use the connection fails with no error. Have to disconnect and reconnect to reestablish vpn.
Pulse Secure version 5.3.3 to SRX220-H2 but confirmed the same with 5.1r1.
PCs do not exhibit the same problem.
Juniper support points me to a kb article concerning large file downloads failing that was apparently fixed in 5.1R12HF1.
Does anyone have any insight as to whether or not this is just a case of Macs don't work and I should look to another solution?
