Function `getAppsInfo()`as used by `serverinfo` provokes IP-ban (Connection refused) by apps.nextcloud.com

I reported this already in the appstore issue-tracker: https://github.com/nextcloud/appstore/issues/1137
I'm posting this here, because I observed this behavior only when the AppstoreFetcher is called by serverinfo.

Steps to reproduce

1. make sure apps.nextcloud.com is accessible:

serverprompt:~# echo -e "\nResponse-Code: $(curl -Lo /dev/null -w "%{http_code}" apps.nextcloud.com)\n==================\n"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   320  100   320    0     0   8396      0 --:--:-- --:--:-- --:--:--  8421
100  301k  100  301k    0     0   271k      0  0:00:01  0:00:01 --:--:--  319k

Response-Code: 200
==================

2. tail -f your logfile: tail -F $(nextcloud logfile) | jq and keep it open
3. open serverinfo in a browser tab
4. whait for log message as below.
5. close serverinfo tab, since the message repeates every 5 minutes.
6. recheck accessibility as under 1:

serverprompt:~# echo -e "\nResponse-Code: $(curl -Lo /dev/null -w "%{http_code}" apps.nextcloud.com)\n==================\n"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (7) Failed to connect to apps.nextcloud.com port 80 after 22 ms: Connection refused

Response-Code: 000
==================

Expected behaviour

no impairments in the connection to apps.nextcloud.com

Actual behaviour

The affected IP get banned/blocked by apps.nextcloud.com.
Since it is my home network, I can easily fetch a new IP but every time a serverinfo tab is opened (no matter what instance, even newly setup in a virtual machine) it get banned again.
Because in my case it's the WAN Ip of my home network, i can not reach the appstore in my browser eather.

}

My workaround:

coment this line: https://github.com/nextcloud/serverinfo/blob/544bacf952cc94ea0d6ec1a828e1de4971acbb94/lib/SystemStatistics.php#L74

//			'apps' => $this->getAppsInfo()

I hope this helps.

Start in lib/SystemStatistics.php at the getAppsInfo() call referenced in the workaround, then trace the /apps/serverinfo/update request and the appstoreFetcher log entry for https://apps.nextcloud.com/api/v1/apps.json. Reproduce the request while monitoring connectivity to apps.nextcloud.com. Done means opening serverinfo no longer causes the appstore connection to be blocked or impaired.
