This is a workaround; not root cause analysis. I'd be really interested to hear if anyone has actually established what the root cause is and how this can be resolved.
I am curious to know if you isolated this issue to any Windows Updates that may have been processed on the server-side? I find the timing of your post, and others having the issue, similar to mine. The only conclusion in my searching for a cause is a recent Windows Update. Have you investigated this further? I am prepping to run a few updates of Horizon to bring it to current and figured these updates will clear the air with any errors with the sdk has invalid credentials, which maybe a result of re-plugging in credentials and configurations in Horizon as I go through the process.
resolved my issue by setting a more complex PW for the AD-User View uses for connecting to vCenter.
Old password was lowercase 4letter 3digit New Password with lots of characters upper&lowercase, digits and special chars.
I have same issue, every couple hours I found this error, but horizon works fine, I can manage every feature but seems every time fail log in vCenter, I have complicated password for user that I use to connect.
I have vCenter 5.5 with Horizon 6.
Have you some help ? for solve this problem.
This issue is still present using Horizon 6.2.1 Build 3284346 / vCenter Server 6.0.0 Build 2776511.
Error message shows up in the connection server log every 1-2 days:
ERROR (0BE0-05DC) <VCHealthUpdate> [ServiceConnection25] Invalid VC login: Check username and password for VirtualCenter VCHealth Test instance at https://<my_vcenter_server>:443/sdk
Did anyone find a solution to this? I am getting the same thing. Using vCenter appliance 6.0 U2 and Horizon 6.2.2. If I use my own account to connect vCenter then I don't get any errors but as soon as I put in the service account, I get the error.
This issue is still present using Horizon 7.3.1 / vCenter Server 6.0.0 Build 5318203.
I had the same issue, it pop's up once and awhile and inputting the creds again fixes it.
