Rails Apnotic OpenSSL alert certificate expired error

Question

I'm trying to send Apple Push Notifications from a Rails app using the Apnotic gem.

I get the following error when I run @ios_client.push(note) .

Traceback (most recent call last):
    5: from /app/vendor/bundle/ruby/2.6.0/gems/net-http2-0.18.4/lib/net-http2/client.rb:114:in `block (2 levels) in ensure_open'
    4: from /app/vendor/bundle/ruby/2.6.0/gems/net-http2-0.18.4/lib/net-http2/client.rb:142:in `socket_loop'
    3: from /app/vendor/bundle/ruby/2.6.0/gems/net-http2-0.18.4/lib/net-http2/client.rb:142:in `loop'

/app/vendor/ruby-2.6.5/lib/ruby/2.6.0/openssl/buffering.rb:182:in `sysread_nonblock': SSL_read: sslv3 alert certificate expired (OpenSSL::SSL::SSLError)

I believe my certificate that I obtained from the Apple Developer account is not expired (I tested by creating a new one), so is there something wrong with my OpenSSL installation?

I get the same error locally and on Heroku. How can I fix this?

Answer 1

Check your certificate, open it by your desktop environment and see if the date is between not valid before and not valid after .

First save your key with .pem

If you are using mac, click the file just saved and press space bar to check valid date
