How do I disable SSL certificate check with nuget command?
PS C:\Softwares> .\nuget.exe list
Unable to load the service index for source https://asd.ca/api/feeds. An error occurred while sending the request. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure.
Please note that I am not planning to upload new package, just wanted to restore my .net packages.
Custom NuGet feed with invalid certificate
I think this issue is related to your nuget Package source feed https://asd.ca/api/feeds or some settings which conflicts with it due to some reasons.
You can try these steps:
Suggestion
First, please make sure that you can access https://asd.ca/api/feeds and can get any request from it and troubleshoot the problem that are not feed addresses.
Second, open VS and make sure that the URL https://asd.ca/api/feeds is checked under Tools-->Options-->Nuget Package Manager--> Package Source and all the urls which are used to restore the nuget packages of your solution are checked.
1) clean the nuget cache or delete the packages folder under C:\Users\xxxx\.nuget
2) open registry editor and then Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client and change the value of this key DisabledByDefault to 1.
3) run powershell as administrator and then type these:
reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:64
reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:32

Besides,also try this function in powershell:
nuget trusted-signers Add -Name xxxxxxx(package source name) -ServiceIndex https://asd.ca/api/feeds.

4) try to change to use another domain on internet Explorer in case the current domain is restricted by certain tools.
5) go to Settings( Global Settings of your PC ) --> Network and Internet --> Proxy --> Automatic Proxy Setup --> and set Automatically detect settings to off.
Hope it could help you.
