    I have logged a docket but I think that might be a waste of time

    Any danger of Teamviewer helping the last dozen posts?

    Me too - same issue since this morning. **bleep** ???

    Yet Another Teamviewer Crash

    We did as well. This is the second time for the last month.

    Me too - same issue since this morning. 

    I have submitted a ticket, but who knows if/when I will get a response.

    Likewise... 1 second "connecting" and back to "ready to connect" on a W10 PC. On a Mac 5 secs...

    Me too... TV is dead at the moment.

    We are having the same issue. It's on Teamviewer's side. Multiple stations and systems are affected. 

    Same here....

    Yeah I've got the same issue as well! Can't establish any connections on a corporate licence. Hopeless.

    Same problem here

    im having the same problem 

    All our techs are having the same issue.

    I have an established connection which has not dropped but can't establish any new ones.

    Seems to be world wide

    it doesn't work.. because i have tried to login on different computers

    I added the following exclusions in Defender on Windows 10 and it seems to have made this problem less frequent. Your mileage may vary.Windows 10 Defender ExclusionsWindows 10 Defender Exclusions

    Just to let you know, I found a fix, I'm not sure it will work.

    My Teamviewer had done this, then next morning it was asking me to loggin again, which I did and then it worked.

    Trying to connect again later, I had the same problem, so I logged out and then back in again and it seems to have worked again. I hope this is a fix.

     

    I saw this error scenario again (TV13 free license). Now remote log has following entries:

    2018/04/27 17:14:01.592  2736  2808 S0   SecureNetworkConnection::SendCallbackHandler(): [ remoteID: ###### connection: 0 remoteConnection: ###### ], Error: SecureNetwork (Connection not found)
    2018/04/27 17:14:01.592  2736  2808 S0!! SecureNetworkImplementation::ReceivedNewRevocationCheck: Error: Connection not found

    When I try connection again after this - it goes ok in my case. I did not need make a forced reset to teamviewer service / process in remote PC....

    Content deleted... I could now see my earlier post...

    Hi

    I found by restarting the client teamviewer session solved this

    I suspect it is a network protocol issue Teamviewer has, 

    I tend to use backup connection type(s) 

    let me know

    Thank you

    Hi The only fix found so far is the restart the host teamviewer, and you should be ok. i suspect it is a teamviewer network protocol issue Let me know I also used another connection type as backup like V.N.C to my client Let me know Thank you

    I see someone has apparently tried to open a ticket, but has been seemingly 'denied' because they don't have a paid subscription.  

    I DO have a paid subscription, but I got Teamviewer as a tool so I could help solve my client's problems - not so I could spend my time helping Teamviewer solve theirs.

    Is there no moderator in these forums?... are they just for entertainment?

    I think ticket needs be opened someone owning a paid license, There is comment on Teamviewer support pages:

    "we are only able to offer support via Tickets to license owners"

    -> I use only free version. Not planning to go for paid license....

    *****************

    fyi,

    I took a look at logs for the case, when I once saw "autentication canceled" scenario for my TV 13 free version.

    In the local PC logs almost identical connection phase (for both success and failed), but unsuccessful scenario has this kind of log entry:
    ************
    2018/04/09 13:48:33.513 323912 323936 S0!! HttpRequestImpl::CurlFinished(): curl request failed: Timeout was reached (28), Operation timed out after 8000 milliseconds with 0 bytes received
    ************

    In a successfull case (local PC logs), the session establishment continues with
    ************
    2018/04/09 13:52:42.377 323912 323936 S0   CHttpConnectionOutgoing::ConnectHttpFastInternal(): Connect HttpFast to server24603.teamviewer.com:80 was successful
    ************

    On the remote PC, logs show some encryption related error ??? -> see 6th row at sample below.

    Hopefully someone on the Teamviewer support has idea, what happens ???
