Error message in log file: Connect to marketplace.atlassian.com failed: Connection refused

Dear Atlassian comunity.
I know that this question has been asked many times, and I have spent couple of days already tried to solve this problem with the help of other users from this forum, but without success.

Error:

2018-08-31 08:06:44,000 ERROR [HealthCheck:thread-8] [plugins.healthcheck.eol.EolSupportHealthCheck] check An error occurred when performing the EOL check, see the exceptions for more info

Setup: Confluence 6.1.3 is running in OpenShift container with the following versions:

λ oc version
oc v3.4.1.12
kubernetes v1.4.0+776c994
features: Basic-Auth
Server https://atlassian.testserver.testgroup.net:8443
openshift v3.9.40
kubernetes v1.9.1+a0ce1bc657

 I have used this (and similar) solutions as reference:
https://confluence.atlassian.com/confkb/confluence-is-unable-to-startup-due-to-marketplace-connectivity-issues-939939190.html

and as suggested the following is set: -Dupm.pac.disable=true and it can be found in Confluence > Systeminfo settings

We have similar Jira setup, and we have same error there as well.

Any fresh ideas are very welcome!

After some time, we figured out that above error is saying "An error occurred when performing the EOL check" which means it has to do something with the eol health check which can be found in <CONFLUENCE_HOME>/shared-home/confluence-healthcheck-eol.json

Solution:
Add the version of Confluence you are using to this file and restart Confluence.
We are using Confluence 6.1.3 so to or our json file we added that version and it looks like this:

 {"versions":[{"name":"6.10","releaseDate":"2020-08-26"},{"name":"6.9","releaseDate":"2020-05-08"},{"name":"6.8","releaseDate":"2020-03-20"},{"name":"6.7","releaseDate":"2020-01-30"},{"name":"6.6","releaseDate":"2019-12-12"},{"name":"6.5","releaseDate":"2019-11-01"},{"name":"6.4","releaseDate":"2019-09-06"},{"name":"6.3","releaseDate":"2019-07-12"},{"name":"6.2","releaseDate":"2019-05-15"},{"name":"6.1.3","releaseDate":"2019-03-20"},{"name":"6.1","releaseDate":"2019-03-20"},{"name":"6.0","releaseDate":"2018-11-02"}]}

and error is gone...
