First of all, a huge thank you to Tom for RUMLog!
But I ran into a problem:
I set up eQSL in the preferences. I uploaded some QSOs and checked them on the eQSL website. All of them are there, some eQSLs already retrieved. Working.
But when I try to use "eQSL in": the software says "Connecting eQSL server" and I get the following window/error:

RUMLog fails to connect to the eQSL server and retrieve the uploaded QSOs. This is very strange....
