The full domain name matching feature cannot match multiple ports under the same domain.

Hello, shuizei. Thank you for writing in.

You can adjust the Autofill behaviour rules on a Login item using the 1Password desktop app. Here's more information on that -> https://support.1password.com/autofill-behavior/.

1. Open and unlock the 1Password desktop app.
2. Locate your Login item and click Edit.
3. Click the Autofill behaviour rule button beside the website URL and choose the Only fill on this exact domain option.
4. Click "Save".

I hope that helps. Let me know if you have any questions.
