Office365 connectivity test:
Hi CocoKola, could you please help me with the following 3 questions?
1. Is TLS 1.2 protocol disabled on your machine?
M365 connectivity test tool service requires TLS 1.2 to establish SSL connections. You may check that on your registry editor to see if it's disabled. You could search "Registry Editor" in the taskbar and open it, then navigate to the following path:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
TLS 1.2 should be enabled to use M365 Connectivity Test Tool .exe client.
2. Are the following two cipher suite on your machine?TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (
0xc030)
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)Cipher suite can also be checked in Registry Editor. The path is:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\CipherSuite
Those two cipher suites are required by the connectivity test tool service.
3. is .NET Desktop Runtime 6 installed on the machine?
This shouldn't be the reason for the SSL connection failure but I see the exception code 0xe0434352 in the crash log you provided in the comment on May 21st, so just want to double-confirm. Is the crash log below from the issue in the original post saying "Unable to connect to origin. Inner exception message: The SSL connection could not be established, see inner exception" shows when executing the rich client?
If the TLS and cipher suites configuration are unknown, you can also try to enable them on the machine using this software or modify the registry through the Registry Editor and see if the issue can be resolved.
The software is NARTAC which can be downloaded from:
https://www.nartac.com/Products/IISCrypto/DownloadNo installation requires. Checking the needed TLS protocol and Cipher Suite should work.
MicrosoftHi CoCoKola ,
When the error pops up, is there any other message below "Unable to connect to origin. Inner exception message: The SSL connection could not be established, see inner exception."?
I launch the downloaded app and I get that pop-up on top of the "onboarding advance tests" , I can click OK and the "onboarding advanced tests" continues to display but nothing else happens.
waited a day and nothing changed. My only action I can take is click on "cancel".

I'm trying to find the root cause of the issue. Could you please help me with the following two questions first?
1. Are you using a proxy to connect to the Internet?
2. Could you please try downloading the standalone connectivity test tool to see if we could get the whole error message? It works quite similarly to the desktop application but in a console.
The standalone rich client could be downloaded here: https://connectivity.office.com/api/AnonymousConnectivityTest/DownloadStandAloneRichClient
After the download is finished you could simply click it and see if the same issue shows up again and if there's more inner error message. There will be consent required after executing the console.
If you run into some problems when using the standalone rich client, here're guidelines for it: https://learn.microsoft.com/en-us/microsoft-365/enterprise/office-365-network-mac-perf-onboarding-tool?view=o365-worldwide#testing-from-the-command-line
or you could comment here.
Thanks.- Thank you fro your reply. No proxies are used.
Downloading the tool I have the same issue, nothing happens. I had seen previously the downloaded app crashed with that pop-up.
I tried launching the direct link above but running as admin and this time I was prompted for permission to run on what looked like a PowerShell terminal pop-up and goes away.
