Facing issues while resolving only one record

[Blason R]

Hi all,

I have bind BIND 9.18.17-1+ubuntu22.04.1+isc+1-Ubuntu (Extended Support
Version)
And I am facing this weird issue. Somehow eportal.incometax.gov.in site is
not getting resolved through DNS.

I tried a lot but unfortunately the issue still persists.

Here are packet capture logs.

I feel this is something related to DNS RRKEY Record size?

Plus then I dumbdb on my server and went through cache using command
*#rndc dumpdb -all*

And here is the output

Any idea what could be an issue?
