Try forcing tls 1.2. This solves most powershell gallery issues
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Not really a solution, but rather an FYI piece.
This also seems to happen regularly every three months now when TLS cert in expires. For some reason, Microsoft are struggling to get the cert renewal to work properly.
When this happens, none of the above mentioned solutions will work. In fact, this is happening right now, as I type this...
To see if the issue is caused by the expired (or otherwise invalid) cert, just open this URL in a browser and see if the browser complains about the certificate.
If you need to make it work just this one time, you can try tricking Powershell into ignoring invalid certificates like so:
[Net.ServicePointManager]::ServerCertificateValidationCallback = {$true};
...but be warned:
a) this is a bad practice and you shouldn't really have it as a permanent solution because this will expose you to man-in-the-middle attack; and
b) this may not help you because Microsoft guys usually disable PSGallery API when this situation happens. To check if the API is disabled right now, run:
# Set-PSRepository -Name PSGallery -InstallationPolicy Trusted

Update: Also look here for any current ongoing issues with PSGallery:
Actually forcing tls12 is not enough to solve, but, reading carefully to the error message said: Use 'Register-PSRepository -Default'
So I tried: register-psrepository -Default
PS C:\Windows\system32> register-psrepository -Default PS C:\Windows\system32> get-psrepository
Name InstallationPolicy SourceLocation
PSGallery Untrusted
And it solve the problem.
