I have TeamViewer 13 Beta isntalled on my PC and my partner too has the same version installed. I unable to conenct my partner's TeamViewer and got the error NOROUTE_NotAllowed while conencting. My partner can conenct my TeamViewer without any issue.
Only differnece that I ahve observed is my OS version is Windows 7 whereas my partner's OS version is Windows 10. Does the OS version has any realtion with this TeamViewer conenction issue.
Below is the error log that I have from my TeamViewer log.
