I’m running into problems with SSL certificate errors when trying to connect to Langsmith. Every time I attempt to establish a connection, I get certificate validation failures that prevent me from using the service properly.
Has anyone else encountered similar certificate problems with Langsmith? I’m not sure if this is a configuration issue on my end or something related to the Langsmith servers. The error messages aren’t very clear about what’s causing the validation to fail.
I’ve tried the usual troubleshooting steps like checking my system time and clearing cached certificates, but nothing seems to work. Any suggestions on how to resolve these SSL certificate errors would be really helpful.
This happens when your local environment can’t verify the certificate chain. I’ve seen it tons of times with API services.
Check if you’re behind a corporate proxy or VPN first. They inject their own certificates and break the chain. You might need to add your company’s root cert to your trust store.
Try connecting from a different network. If it works on your phone’s hotspot but not your main connection, it’s definitely a network issue.
Update your Python requests library if you’re using Python. Outdated certificate bundles cause these validation errors.
Worst case, disable SSL verification temporarily to test if everything else works. Just don’t leave it like that in production.
Had the same issue last month - drove me absolutely nuts for days. Fixed it by updating my system’s certificate store. On Windows, run certlm.msc and refresh certificates. On Linux, update the ca-certificates package. Langsmith was using a newer certificate authority my system didn’t recognize. Also check if your company runs SSL inspection tools - they mess with external API connections all the time. Corporate security tools love causing validation errors with cloud services like Langsmith.
i had this happen too! turns out my antivirus was blocking the connection. maybe check firewall settings or adjust your antivirus config? it might help clear up those cert issues. gl!
