[Errno 111] Connection refused

[subject-am]

Hi, I'm trying out the chembl_webresource_client for the first time, but I keep getting the same error every time I import new_client. Can you understand what's causing the problem from the error?

Hi, I can't reproduce it now but still happy to help. I would check two things:

1. Do you have internet access?
2. Can you check again to make sure that wasn't a temporary glitch.

[subject-am]

Hello, 1) I did have internet; 2) It most likely was, because I tried again today after seeing your reply and it just accepted, with no errors!

Thank you so much for your attention!

[mnowotka]

I'm glad to hear that! My apologies for a very late reply. If you happen to have any more problems like this please create another issue and I promise to be faster this time :)

[subject-am]

Don't worry about it, I understand that sometimes it's not possible to reply as soon as we'd like. As I'm just starting to work more with ChEMBL now, there might be a few :P Thank you you once again for the help!

In that particular case GitHub notifications were redirected to the wrong email address and I coudn't see them. It took me some time to figure this out but now it's fixed.
