Hi! @printer0, Welcome to HP forums.

I understand when you try to scan to email you are getting server connection error from your printer.

Don't worry I'd love to help you out.

Did you make any changes to your printer?

Have you enabled web services on your printer?

Please try the steps recommended below.

1. Go to System Preferences > Print & Scan
2.  Right (or control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
3. Select the plus sign to re-add a printer. Select the Default tab on the top of the window. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
 

Assign google DNS address to your printer and check if it helps.

1. Obtain your printer's IP address

a. This can be done by pressing the wireless icon on the printer.

2. Enter the printer's IP address in a browser.

3. Select the network tab at the top of the page.

4. On the left select networking.

5. Select Network Address (IP)

6. Select Manual DNS Server

a. Manual Preferred DNS should read 8.8.8.8

b. Alternate DNS Server should read. 8.8.4.4

7. Select apply you might get a warning just select okay.

Hope to hear from you soon!

Have a wonderful day ahead! 🙂
