I cannot update my projects anymore via composer. 3 days ago out of the blue this error occurred:

curl error 60 while downloading .json: SSL certificate problem: unable to get local issuer certificate

I can update composer when "disable-tls" is set to True, but "composer update" still gives error above.

On my laptop and and other (windows 11) computers the curl command

curl  

gives error

curl: (35) schannel: next InitializeSecurityContext failed: CRYPT_E_NO_REVOCATION_CHECK (0x80092012)

So i assume curl is the problem, something with finding the certificate.

On my second computer there is no PHP or something like that, so it really is a windows 11/curl problem.

Also important to know, is that on my old windows 10 laptop the problem is not there!

How to get curl reading the certificate?

Thanks to this i got the answer!

All HTTPS connections outside of browser fail with "SSL certificate problem: unable to get local issuer certificate"

I am using Norton Antivirus, and I disabled the "HTTPS Scanning" option within the "Safe Web" feature.

This prevented the original curl error 60 in composer.

For reference: https://curl.se/libcurl/c/libcurl-errors.html#CURLESSLCONNECTERROR

CURLE_SSL_CONNECT_ERROR (35)

A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.

https://curl.se/libcurl/c/libcurl-errors.html#CURLEPEERFAILEDVERIFICATION

CURLE_PEER_FAILED_VERIFICATION (60)

The remote server's SSL certificate or SSH fingerprint was deemed not OK.
