How to solve the error "zlibinstream: above bytesIn" in vnc

Question

From time to time I get the error "zlibinstream: above bytesIn" when trying to connect to my server through my vnc. Why am I getting this error and how to solve it when I get it - without rebooting my server?

Answer 1

The same question has occurred several times. I don’t know about the permanent fix, but for quick, just change the color to Fullcolour.

For me in VNC Viewer, this was in the / Expert / FullColour options for true.

Answer 2

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

Prior to this, Burpy Burp's answer to changing the / Expert / FullColour parameters to true temporarily fixed the problem, but he returned after 22 days.

Answer 3

This seems to be due to timing. On my mac, I have the same problem and usually wait some time, and retrying is the only thing that works for me. He always returns, but is not an immediate decision.

Answer 4

Just for googlers who find this question: changing the “preferred encoding” to something other than “ZRLE” (I used the “hextile”), this is what solved the problem for me.

Answer 5

Another quick fix (for Mac):

Reading other answers and trying out a few, I feel that random properties / parameters will "solve" this problem. For Real VNC on Mac, follow these steps:

Options → Image Quality → High. Then return it to the "Automatic" position.

Answer 6

In my case, the solution is simply to change the quality to Low . This seems to be normal.

Answer 7

Opening the options dialog without changing anything did this for me. Upset .
