Pulse secure is unstable in Windows 10

How do we troubleshoot what's causing Pulse Secure VPN to be unable on Windows 10?  It seems to randomly drops the VPN.  On the same computer, my ssh sessions are stable so it's not the network.

Sometime it would go for hours and other times it could disconnect several times in a minute.  On the same network, Pulse Secure is extremely stable on the Mac.

 

Looking at event viewer, I see the following errors with respect to Pulse:

 

Error connecting channel.

 

Network error.
System error (10054):An existing connection was forcibly closed by the remote host.

 

Reason (6): agentd error
Server detected error.

 

Error connecting channel.

Re: Pulse secure is unstable in Windows 10

Hi @vamfoom ,
This issue can be caused by many things.  In our lab it was the 9.1R3 back-end upgrade (issue every 10 mins / upgrade to 9.1R4 solved it). 
In the production enviroment (enterprise) we're suspecting the external firewall which gives Deny's on Port 80. You might also want to check host firewalls. 
KB article about issue that i've found

Good luck!

Did enabling port 80 solve your error=10054?

Re: Pulse secure is unstable in Windows 10

Didn't test it as we only want to have HTTPS and we did not redirect the port80 toward port443

 

with error=10054, can be many things and you also need to check the logs around it to understand what is happening. 

Sometimes i noticed this behaviour on CaptivePortals which weren't properly configured.

Re: Pulse secure is unstable in Windows 10

can you check which connection type you have on windows, please, by opening the pulse client and right-clicking on the connection to show connection details?
it is possible that the windows connection type is different than the mac type
