Thanks for thaking the time to document this. I was tearing my hair out and clearly not reading the error message correctly.
Hi Jurski,
Thanks for your response.
We are currently working on the site on a local server that is not publicly accessible.
It dawns on me that there may be an issue with our firewall blocking access to non-standard ports. Do you know if the system uses specific ports?
I will get it migrated to a public dev server in case this is not the problem.
Thanks for your assistance and Kind Regards.,
Oliver
