Network Connection Unreachable/Portal Unresponsive

[AlexMcCreery]

Has anyone seen this error "The network connection is unreachable or the portal is unresponsive. Check the network connection and reconnect" while on their company internal network?

I recently got this while at one of our locations and did the following:

1) rebooted

2) turned wifi off and on

3) connect to ethernet

And nothing has worked. I went moved to a different onsite location (also internal) and my connection came up fine. It only seems to impact some users while onsite and only at a few of our sites.

To note, my co-worker was sitting right next to me at the same site, on the same wifi, connected to GP. It seems random at the moment and the only solution is to

1) connect to hotspot

2) auth in and auth to an internal site

3) switch back to internal network

Everything works from there.

Any help is appreciated!

Hi @AlexMcCreery ,

Hope you are doing well. Quick question, do you manage the Palo Alto firewalls or GP config directly? The reason I ask is because it doesnt seem like there's an internal gateway configured for GP.

When you’re on the internal network, your client tries to connect to company.gp.com. But your traffic gets NATed behind the site’s edge firewall or router, possibly getting a public IP that might not be allowed or routable to the portal/gateway address. I would double-check with the local network team/firewall team at your site to see what traffic looks like headed to your portal. 

Also, when you are in-office and connected to the employee wifi or directly connected, can you access the internal sites from there? Wondering why you are trying to connect to GP when youre already on the internal network.

Hi @JayGolf,

I should have clarified. Out GP is set to always on. We don't have an internal gateway yet, but we do check for an internal server (if it resolves then you are on the internal network).

When it happened to my machine, I was sitting next to my coworker that has the same GP configs as me and he worked with no issue. I shutdown, rebooted, refreshed my connection, disconnected/reconnected, turned wifi on and off (I didnt have an ethernet cable to test wired but I have seen it not work with other users). It wasn't until I connected at our main office building wifi did it all of the sudden came back up.

Palo suggested a timeout but not sure that really applies when two machines right next to each other, doing the same lookup, early in the morning, connecting to the same AP and one can connect just fine and the other cant

Just odd, hoping we aren't the only ones who have seen this and someone has a better solution than connecting to hotspot and then reconnecting to the internal network.
