pgadmin4 - centos7 - "The application server could not be contacted"

Hi,

I recently did some yum updates and just said yes to all the updates. And since then when I open pgadmin4, I get the message "The application server could not be contacted" and pgadmin4 does not open. I searched around, and it looks like this is common on Windows, but I've only seen one mention of this with Centos with no reply.

Hi. An attempt to start pgadmin4 yelds message box with "The application server could not be contacted." error. Is there any logs or something I can check? Name : pgadmin4-v1 Arch : x86_64 Version : 1.5 Release : 2.f25 Repo : @System From repo : pgdg96 Linux 4.10.14-200.fc25.x86_64 Fedora release 25 ...

I checked the pgadmin.log and there's nothing in there that would provide me any useful any information.

My last entry was for a disconnected connection:

2018-04-10 22:09:50,025: ERROR pgadmin:
Failed to execute query (execute_async) for the server #1 - CONN:5683531
(Query-id: 949081):
Error Message:ERROR: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

I renamed the folder, and no changes.

Any help would be greatly appreciated.

Thanks,

Alex
