how to solve the “zlibinstream:exceeded bytesIn” error in vnc

Question

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 ?

Answer 1

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.

Answer 2

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

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

颜色级别完全没有解决问题，但设置选项 - 图片质量高而不是自动解决。

Answer 7

只是为那些发现这个问题的googlers：将“首选编码”更改为“ZRLE”以外的其他内容（我使用“hextile”）是解决这个问题的原因。

Answer 8

Opening the options dialog without changing anything did it for me. Baffled .
