I couldn't even connect to otr.im using standard obfs. It took forever to initialize the stream. My ISP got merged with someone else; so I decided to use obfs4 and it works flawlessly.
Tor Browser works just fine which I find it very odd.
Anyone using Tor Messenger? Try connecting using 5rgdtlawqkcplz75 dot onion. You will be prompted with a security exception - just add it.
Now I can use it just fine. FYI. I can't name my ISP for opsec reason.
EDIT: to MOD - no, I am not on Comcast. LOL!
EDIT: If I recall correctly... riseup.net is already compromised by the FED, no?
EDIT: Now it seems to be working (otr.im onion version, except riseup.net).
Literally has terrible ideas about ospec
