Lync 2015 Mobile issue (Network Steve Forum)

Lync 2015 Mobile issue

Hello everyone,

We have 3 Skype for Business Server 2015 servers at each remote office. Users in office 2 get the error when sign-in to their Lync Mobile (happens to iPhone, Android) - "We can't connect to the server. If you're using Wi-Fi, open your browser to see if you have a connection. Otherwise, disable any hot-spot or tethering connections. If the problem persists, contact your network provider." If I move them to another pool then the issue is gone. The Lync on desktop works fine for users in office 2. Any ideas?

Thanks,

Hi IT-newbie,

You may try the following suggestions.

1. Make sure the external web service DNS records exist. (I assume that you have multiple FE Pools)

2. Maybe the proxy is not correct configured, check the configurations on Reverse Proxy.

3. Check the network between Office 2 and Office x where the Reverse Proxy resides.

4. Please check the IIS application state on the SFB servers which in Office 2, ensure the application is running.

5. Check the event logs on the SFB servers.

Best regards,

Eric

Thank you Eric for your reply. As I am new in Lync and not the one who set up Lync, so I will have some stupid questions :). Please see my notes below:

1. Make sure the external web service DNS records exist. (I assume that you have multiple FE Pools) - as we don't have any issue with office1 and office 3 pools so the external DNS should be fine, is that correct?

2. Maybe the proxy is not correct configured, check the configurations on Reverse Proxy. Could you please give me more details? We use IIS for Reverse Proxy and all servers in Server Farm are green.

3. Check the network between Office 2 and Office x where the Reverse Proxy resides. I can ping from office2 front end server to reverse proxy in office1

4. Please check the IIS application state on the SFB servers which in Office 2, ensure the application is running. - the LyncUCWA started on the front end server in office2

5. Check the event logs on the SFB servers.

Best regards,

Eric

I've got this report from MS Lync Connectivity Analyzer tool. Only the account belongs to office2 has the problem, if I move this account to another office1's pool then it works. Any ideas?

Thanks much!

Check if the link https://Prod-lync-01-v.int.mydomain.com/WebTicket/WebTicketService.svc is accessible.

If it is accessible, then you'll be prompted for credentials.

Hello Eric,

The https:\\xxxx does not works ( The page cannot be found) but the Http:\\xxxxxx works - prompt for credentials.

What should I do next? And why users in the office1's pool and office3's pool do have any issue with Lync Mobility?

Thank you so much for your time.

Hi IT-newbie,

Do you have the second NIC on the FE server ?

Hi Eric,

Sorry for the late reply, I've been busy with another projects. No, we only have 1 NIC for FE servers and reverse proxy server as well. For now, the workaround is moving people to another pool. :( I've tried to narrow down the issue and hope you have a second eye on this:

On problematic pool, test user can sigh-in to Lync desktop but not for Lync Mobile ---> Lync/Internal DNS works fine

Move test user to another pool ----> both Lync Desktop and Lync Mobile work fine ---->Internal DNS/External DNS/AutoDiscover/Reverse Proxy work fine.

Got this error from LCA:

[ERROR] Couldn't connect to URL https://Lync-domain.local/Autodiscover/AutodiscoverService.svc/root/user?originalDomain=domain.com?sipuri=test@domain.com
[ERROR] Reason: Internal server error (HTTP status code 500)
[ERROR] InternalServerError: Source server FQDN: Problematic-Server.domain.local\r\nReason: No valid security token
[DEBUG] System.Exception: Exception of type 'System.Exception' was thrown.

The connection between problematic office and HQ office is good. It seems the test user can't authenticate and that makes me think about certificate issue but I don't know how to test that properly.

Thanks,

If I want to uninstall Lync on problematic server and then reinstall, where I can find the document to do it properly?

Hi Eric,

On problematic pool, test user can sigh-in to Lync desktop but not for Lync Mobile ---> Lync/Internal DNS works fine

Move test user to another pool ----> both Lync Desktop and Lync Mobile work fine ---->Internal DNS/External DNS/AutoDiscover/Reverse Proxy work fine.

Got this error from LCA:

The connection between problematic office and HQ office is good. It seems the test user can't authenticate and that makes me think about certificate issue but I don't know how to test that properly.

If I want to uninstall Lync on problematic server and then reinstall, where I can find the document to do it properly?

Thanks,

Hi IT-newbie,

You have 3 FE servers in each pool, right ?

If you need to reinstall one of the FE server in the pool, you can just reinstall it. (Reinstall the OS with the same computer name and then run Lync Deployment Wizard.)

Best regards,

Eric

Hi Eric,

I went thru the removing FE from the pool; adding it back to the pool (published topology after each step) but the problem still persists. Just let you know and I'll keep you posted.

Thanks,
