So what does it (the registry HKey) say at the moment ? Is it just the single sub-key SSL 1 ?
Please try and see whether the registry change works for you as it has - so far - for me.
Tap Windows key, type regedit in search box and double click on the resultant regedit.exe file
I had a bit of trouble initially finding the correct area to edit and found this article helpful https://www.lifewire.com/hkey-local-machine-2625902
Then do what Clitheroe Kid said:
navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
If the TLS 1.1 and TLS 1.2 subkeys are missing (i.e. if the "Protocols" key only has a single subkey named "SSL 2.0"), you need to create them manually. Here's how to do so:
- Right-click on "Protocols". Select "New", then "Key". Name the new key "TLS 1.1" (without the inverted commas).
- Right-click on that new key, then create another key underneath it named "Client" (without the inverted commas).
- Right-click on the new "Client" key. Select "New", then "DWORD (32bit) Value". Name the new item "DisabledByDefault" (without the inverted commas). By default, its value is zero (which is what you need, so leave it as that).
- Right-click on "Protocols". Select "New", then "Key". Name the new key "TLS 1.2" (without the inverted commas).
- Right-click on that new key, then create another key underneath it named "Client" (without the inverted commas).
- Right-click on the new "Client" key. Select "New", then "DWORD (32bit) Value". Name the new item "DisabledByDefault" (without the inverted commas). By default, its value is zero (which is what you need, so leave it as that).
Here is a link to an image which shows what the fixed registry should now look like:
I hope this works for you - and I hope it continues to work for both of us long term without throwing up further difficulties.
