I just recently upgraded to version 7 and now when I connect to host also upgraded with version 7 the connection drops and reconnect about every 20 - 30 sec. Didn't have this issue with 184.108.40.206 (69110). The interesting thing is I still have some host I didn't upgrade to 7. They are still running 220.127.116.11 and those connection don't drop. There is a problem in version 7. I run my own RUS. That is also running the latest version.
Could you please clarify if you use version 18.104.22.168 of Remote Utilities? If this is the case, then please note that there was a minor issue in version 22.214.171.124 that was causing frequent disconnections. However, we've already fixed the issue and released an updated version 126.96.36.199 with the implemented fix.
The updated 188.8.131.52 version is available for download on this page. You can also use the Automatic update (or self-update) feature. Please make sure to update both Host and Viewer to the same version in order to avoid the version mismatch.
