Good afternoon-
Afer installing S4B 2019 I am unable to start the service. I examine the event logs under Lync Server and the error code 47067 appears as well as 56010 and 56011. I have addressed the certificate issue by cleaning out the cert stores but still cannot get the service started. I have been troubleshooting via Google and followed advice found but no joy.
I cannot paste logs since system is on another network and cannot post them
Any help would be appreciative
-Brett

Hi @Brett H ,
Can you provide a detailed screenshot about your event ID description?
Have you tried to check your status of front-End Service?
Do you have any operations before this issue occurred?
In my experience, there are several factors which can cause this issue. If your error message shows “Network connectivity
issues or an incorrectly configured certificate on the destination server”, we recommend you try to run the following command to check the certificate installation path. If there is certificate information in the c:\computer_filtered.txt file, you can determine the certificate name according to the "FriendlyName" in it, and then check if the corresponding certificate is installed correctly in the certificate management console.
Get-Childitem cert:\LocalMachine\root -Recurse | Where-Object {$.Issuer -ne $.Subject} | Format-List * | Out-File "c:\computer_filtered.txt"

Good Morning Jimmy-
Unfortunately cannot provide a screen shot since this is on another network that does not have connection to the internet..its an inside facing network only..
When I check front end service it simply says starting..does not go to running...so it does not start
This is our first attempt with S4B 2019 and we have not been able to successfully have it up and running
After I ran the command..I received output of 8 certs but all their friendly name is blank and I'm not sure if thats looking at the Trusted Root or Third Party Root
BTW- after reviewing the Cert store- I do not see a cert for Skype for Business 2019 within the Cert store as seen in this link:
Error log output from Event Log- error 47067
Jimmy-
Wanting to follow up- please advise
Hi @Brett H ,
Sorry for delay reply!
In this case, we recommend you go to Skype for Business Server Deployment Wizard and click the Install or Update Skype for Business Server System. Then locate the Request , Install , or Assign Certificates and click Run Again. Make sure you have installed these certificate in your server.
Good morning Jimmy-
I reran the cert installer and receiving the same error code-47067 and the Skype for Business just says starting
Also receiving 25065 - The Mediation server Service has encountered a major connectivity probem with the Front End
In addition - in the certificat wizard- where it shows OAuthToken Issuer it is shoing the old Lync server cert rather than Skype- should I remove that and install the S4B cert there as well??
Hi @Brett H ,
Have you deployed old Lync Server in your environment before?
You can remove the old cert and install the Skype for Business cert to see if it works.
For more reference about Skype for Business Server certificate deployment, you can refer to:
Jimmy- We are attempting to migrate from an old Lync server to S4B2019 on a new server..
I was able to remove the old Lync cert and assign the new S4B cert into the OAuth field
In addition- do the certs need to be the same ..in other words the local cert be the same as the global cert...
Hi @Brett H ,
Yes. Regarding certificate deployments in Skype for Business Server, you can refer to the following blog:

This started happening a lot randomly for us. We ended up moving all our chats to Teams and our phone calls to a free program called MicroSip (Our on prem phone server doesn't support teams integration).
It seems any time a certificate is messed with, usually some kind of Azure AD cert gets automatically put there, or if by accident we have a cert autoenrollment with group policy, etc.... it crashes the Skype front end service. I don't know why its so unstable, but my guess is Microsoft wants people off of it and go to teams. Thing is it worked really nicely in our environment not just for chats, but for enterprise voice as it had a direct sip connection to our on prem phone system environment. With Teams in the cloud, we don't have that, so finding MicroSip was a real nice win for us.
