Keep getting disconnected since updating to 1.7.10 (1459) to
Posted: Fri Jul 06, 2018 1:10 am
I updated to the latest version this morning and since then have been getting disconnected roughly every 10 to 20 mins and forcing me to quit viscosity and restart it again. I've taken some of the advice re ping and ping restart times, both of which were 0 before I changed them to the suggested 10 and 3600 which hasn't made a difference. My log keeps showing the message
2018-07-05 15:55:58: WARNING: INSECURE cipher with block size less than 128 bit (64 bit). This allows attacks like SWEET32. Mitigate by using a --cipher with a larger block size (e.g. AES-256-CBC).
I don't know if it's connected to the disconnection as i've never looked at the log previously so have never seen it before today.
I just restarted viscosity a moment ago and the log gave the following
