## Solution number 1:

 Most of the time the problem is caused by there is no match between the set of cipher_suites supported by the machine hosting Synchronizer and the set of values that our server was able to accept. 

1. Open the Registry Editor.
2. Go to HKLM/SOFTWARE/Policies/Microsoft/Cryptography/Configuration/SSL/0010002
3. Check if you have there any of those values:

It needs to have at least one of them as those are cipher suites used by our infrastructure. If none of them is present add one (do not forget about making the backup of the registry!) and reboot the machine. 

## Solution number 2:

1. Download and install [IISCrypto](https://www.nartac.com/Products/IISCrypto/)
2. Go to the Cipher Suites tab:
  
3. Check if you have checked any of those ciphers:

If not, check it and reboot the machine.
