Lost Access to Web GUI on PopOS! system after Zoiper install

General Help
1

I am brand new to FreePBX. This week I installed a FreePBX 17 virtual machine in Proxmox.

I registered two Yealink T58 phones.

I registered one Zoiper soft phone on an iPhone.

No issues so far but then I installed the Zoiper soft phone app on a Pop!_OS (Debian based) computer. This is the main computer I work from. Not only was I not able to get the soft phone working but I somehow lost access to the web GUI (tested on Firefox, Chrome, DuckDuckGo).

I can access the web GUI from another Win11 computer.

I uninstalled Zoiper from the Pop!_OS machine but still no FreePBX web gui.

What happened?

When I log into the Proxmox console I see that when I log in to FreePBX it says in Red

“NOTICE! You have 5 notifications! Please log in to the UI to see them!”

Where in the gui can I see these 5 notifications?

Can you reach the system from another device?

I suspect you have Zoiper misconfigured (port, password, etc.) on the Pop!_OS system and the FreePBX firewall has locked your IP address out due to too many invalid login attempts.

Yes. I can log in to FreePBX from a Win11 computer.

I agree. I know Zoiper is misconfigured. I wanted to log back in to FreePBX to fix Zoiper. That is when I realized I was not able to log in to it anymore. Later I realized I could log in to Free PBX from a Win11 pc.
I uninstalled Zoiper in Terminal with the following command

sudo apt purge zoiper5

It gave me the following response:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package zoiper5

I will try to get Zoiper properly uninstalled and post if that fixed it.
