SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (37 answers)

Closed 5 years ago.

I'm setting-up Redmine to poll e-mails from gmail via IMAP. An attempt to run the appropriate Ruby task causes the following error:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

The error occurs when Ruby attempts to connect imap.gmail.com via OpenSSL, in the following code line:

imap = Net::IMAP.new(host, port, ssl)

When I try to connect the above host from OpenSSL command line, it gets connected successfully.

I understand that Ruby doesn't find some certificates and I saw various solution proposals, but unfortunately I still can't figure out how to sort out this issue (I do not use rvm).

I tried to disable the verification by setting OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE, but got "dynamic constant assignment" error.

My environment:

Linux debianvm 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

The issue has been solved by simply installing root certificates:

apt-get install openssl ca-certificates
