how to solve the "zlibinstream:exceeded bytesIn" error in vnc

Every now and then I get the "zlibinstream:exceeded bytesIn" error when trying to connect to my server through my vnc. Why do I get this error and how can I solve it when I get it - without restarting my server ?

Came across the same issue a couple of times. I am not aware of permanent fix, but for a quick one just change colour to Fullcolour.

For me in VNC Viewer it was in options/Expert/FullColour to true.

Another quick fix (for Mac):

Reading the other responses and trying out a few, I feel toggling random Properties/Options will "solve" this problem. Do the following for Real VNC on Mac:

Options -> Picture Quality -> High. Then Set it back to Automatic.

Color level Full didnt resolve the issue but when set Options-Picture Quality High instead of Automatic resolved.

In my case the solutions is just to change quality to Low. Seems to work fine.

What worked for me was to turn off "Adapt to network speed (recommended)" (under Options->Display) and then move the compression slider to the left from "All available colors, medium compression" to "Hundreds of colors".

Prior to this, Burpy Burp's answer of changing options/Expert/FullColour to true temporarily fixed the problem but it came back 22 days later.

This seems to be related with timing. On my mac, I'm having the same issue and usually waiting for a while and retrying is the only thing that works for me. It always comes back but not an immediate solution.
