@haoxingxing thanks for submitting the issue, I think some effort would be needed to reproduce this. On initial look it might be a bug with multiformats lib which might be assuming no additional ports with https (defaults to 443). This is a weird edge case, would you like to investigate and submit a PR for this issue?

I knew little about js so it might be difficult for me to direct contribute to the code.

But i think the issue is a local problem because it is normal to set the ipfs api address with custom port the two settings (api/public gateway) should have similar processing logic but one is normal and the other not
