Jira on-premise: Display errors and performance issues

[charmony]

Hi, I'm in the process of figuring out why this happens or where to start.

Basically, we are using Harmony and added Jira on-premise as an app, opening it works, but we are dealing with display and performance issues.

Display issues: as seen below, under "Projects" a list should open as well as the system dashboard should be filled with content. But it's all blank

Performance issues: Sites take ages to load.

Confluence on-premise, which is hosted on the same server (Debian, nginx) in the background, runs perfectly fine. No issues there.

What additional infos can I provide to help out here? Where to start?

Cheers,
charmony

Let's start with the basic information:

• Version/JHF of the gateway you are connecting to
• Version of the Harmony client with deployed blades

Is there anything in the logs that occur when the client attempts to connect?

We should be using the latest cloud version, see https://support.checkpoint.com/results/sk/sk155574

Can I check version number in the options somewhere too?

Also, users connect via https://eu.connect.checkpoint.com/[OUR_COMPANY_NAME]

Logs show me that the user can access Jira as granted per policy and GET/POST requests show up as well:

Does this info help?

This is a Harmony Connect question, which means the questions I asked about versions is not entirely relevant.
This will probably require TAC assistance: https://help.checkpoint.com
