Cannot list repositories - Failed to connect to Docker

[svink123]

In the docker config menu, it is failing to connect to docker and load the repositories:

Even though the URL is accessible from the browser and the list is not empty:

I ran the service using: sudo dockerd --tls=false -H=tcp://127.0.0.1:2376

I'm having the same problem, though I enabled TLS on mine. Ever figure it out?

Has anyone figured it out?

Hello there, I think that the Docker API has changed again. After doing something like #28, you should also change the 262 line in __init.py__:

for i in r.json():
       if not i['RepoTags'] == []: # Change this from None -> []
           if not i['RepoTags'][0].split(':')[0] == '<none>':
               if repos:
                   if not i['RepoTags'][0].split(':')[0] in repos:
                       continue
               if not tags:
                   result.append(i['RepoTags'][0].split(':')[0])
               else:
                   result.append(i['RepoTags'][0])

Hope it helps.

Hello all, has anyone found a working solution to the "Failed to Connect to Docker" issue? I used the latest files and manually confirmed my Dockers we're up and the APIs could connect manually, but no luck within the plugin /config UI.

Hey @martygcyber , it's likely that TLS may be failing or something. There was also this weird issue where sometimes you needed to save the TLS keys a certain way (that the script handled) and then one day it just changed to saving it another way (and it keeps going back and forth, and I haven't sat down to figure it out yet).
Try to check the temp folder for the certificates when the instance is running (CTFd) to see if they look proper. A key giveaway would be if they are in Windows (DOS) format or if they have \n or \r\n strings literally in the file.
Finally, The "Failed to Connect to Docker" error is generic. It may just mean there are no repos to display, though I'm not saying that's what you're experiencing. I hope this helps.
