Go Modules in Local/Private Forgejo Instances

Bit of a newbie question here, but I’ve set up a local Forgejo server in my homelab that I’m using for personal projects. I’ve created some modules that I want to be able to reference in other local projects.

Trying to run

go get code.mydomainname.com/tapdattl/test

returns

go: downloading code.mydomainname.com/tapdattl/test v1.0.0
go: code.mydomainname.com/tapdattl/test@v1.0.0: verifying module: code.mydomainname.com/tapdattl/test@v1.0.0: reading https://sum.golang.org/lookup/code.mydomainname.com/tapdattl/test@v1.0.0: 404 Not Found
        server response: not found: code.mydomainname.com/tapdattl/test@v1.0.0: unrecognized import path "code.mydomainname.com/tapdattl/test": https fetch: Get "https://code.mydomainname.com/tapdattl/test?go-get=1": dial tcp <my netbird ip address>:443: connect: connection refused

However I know my Forgejo server is up, and I can push to it and clone from it and do all the normal Git workflows. But Go apparently can’t talk to it.

Can anyone explain what’s going on?

Thanks!!
