OpenBullet 2 can't check proxy.. Help

Hello everyone. I have a really big problem, all my proxies are “not working” in openbullet. My proxies work on open bullet 1.2.2 but with higher versions all my proxies (different providers) are “not working”. Can you help me ? Thank you all

Make sure you are on the latest version 0.1.26 as the one before that had issues with proxies.

Hello,
Did you import them correctly?
Have you chosen the right type of proxies?
Have you looked at the default proxies in your setup?
Have you tried with different proxies like for example this on this free site:
