Unable to Verify Custom Domain with Firebase Using

问题:

After I followed the instruction by inserting the Text Record 1 that firebase has provided into my NameCheap, this error message keeps popping up:

Current Status: Sorry, we were unable to verify your domain.

This message has been shown up for about 5 days now.

I've captured screenshots of firebase and namecheap setting as below:

After @Frank van Puffelen suggested to change the host value from my domain name to @, this is the screenshot, and we'll wait and see after a few hours, hopefully it can verify successfully.

After waiting for a few hours this message appears:

From other reports and the information on this Google page for verifying namecheap domains, it looks like you may have to use @ for the host field.

Can you try that? If it doesn't work, let me know and also reach out to [e-mail].

Your attached screens do not show your CNAME configuration. Even though firebase instructions indeed only asks for two TXT records, records that are both correctly set up as your screens show, I believe that these pair of TXT records that firebase requests do not free you up from the need of setting up at least a CNAME record in addition to both TXT records.

This was my case: while I did not set a CNAME record, firebase never recognized my domain.

I am not an expert (sorry!), but in the lack of other answers, even I may be helpful to suggest that you set up your CNAME record to point to:

CNAME record
host: www
value: [yourfirebaseappname].firebaseapp.com.
(Please note the dot after the '.com').

In my case this was enough to make firebase works well and recognize my domain.

In my specific case, and I'll register here at least for my own future use, I prefered to use, as an after step, both A records supplied from firebase as my way to route to my domain without www.

I believe this can be done with CNAME, but in my case the final setup was:

Advanced DNS Management
type: CNAME record
host: www
value: [my-domain-name-without-www]

type: A record
host: @
value: [IP address from firebase, like '1.2.3.4']

type: A record
host: @
value: [Second IP address from firebase, like '2.3.4.5']

Everything is working fine using this configuration. Goal reached.

As a todo future step, It would be useful to learn how to achieve similar goal using the CNAME record pointing to firebase domain instead of A records pointing to firebase supplied IP addresses.

Hope this helps other users in similar situation!

I had issues connecting my custom domain as well, apart from using @ in the host field and the CNAME, you'd also need A records. Here's all I ended up with, I sat back a while for the domain to get propagated (I had just purchased it) and waited for 10 minutes after adding all of the records and it worked. Also I've found helpful instructions in this blog post.
