Just released a new 4.15 binary build, but I’d recommend trying the build yourself once to see that it’s not that bad overall 
Update to 0.4.8
-Includes changes from 0.4.2 to 0.4.8
-UTF8 support
-4.15 compile fixes (thanks @KenshiHH)
-Session ID fixes
-Connection fixes
grab latest release at the usual https://github.com//socketio-client-ue4/releases
If you’ve had disconnection hangs, try the new version and let me know if it fixes things for you.
