Original GitHub issue: https://github.com/1Remote/1Remote/issues/1023

Originally assigned to: @VShawn on GitHub.

Yesterday I was still able to copy text/code from the remote machine (including PyCharm) to my local computer through 1Remote without any issues.
However, starting from today, clipboard synchronization stopped working completely.

Even simple text copied from Notepad on the remote side cannot be pasted on the local side.
Local clipboard works normally (local-to-local copy/paste has no problem), so this issue seems specific to 1Remote’s remote-to-local clipboard channel.

No configuration changes were made on either machine. The issue appeared suddenly.

Environment:

Local OS: Windows

Remote OS: Windows

Application: 1Remote

Clipboard Sync: Enabled on both sides

Both machines restarted

Reconnecting the session does not fix the problem

Expected behavior:
Copying text from the remote machine should sync to the local clipboard normally (as it did yesterday).

Actual behavior:
Copying any text (e.g., from Notepad, PyCharm) on the remote machine does not appear in the local clipboard.
The paste operation on the local machine always results in empty content.

Additional notes:

Local clipboard is functioning correctly

The issue affects all applications on the remote side

Suspected that 1Remote clipboard synchronization channel fails to initialize

I occasionally encounter clipboard malfunctions when using RDP. After investigating, I found that the issue lies with the rdpclip.exe process on the server side. In such cases, simply killing the rdpclip.exe process from the Task Manager and then restarting it resolves the problem.

Both machines restarted

However, my situation differs from yours, as restarting the machines actually fixes the issue.

Hey, i have updated to version 1.2.1 recently and now notice the same problem with the clipboard. What i also noticed is, that when clipboard bugs out, other things dont work either anymore, like proper mouse "transfer", so functions like click and hold or scrolling are no longer working, which is insanely annoying, if i am no longer able to scroll or resize windows in a remote rdp session.

@Joly0 Actually, I have no idea what causes the clipboard to stop working.

In the MSTSC.DLL provided by Microsoft, a single rdpClient.AdvancedSettings9.RedirectClipboard = true enables the clipboard feature, and this part of the code hasn’t changed since version 1.0.

The occasional clipboard failure makes me think it’s related to the system. e.t. there was a period when my clipboard frequently stopped working, but it hasn’t happened for a long time now. During that time, I only kept the system’s automatic updates enabled and didn’t make any other changes.
