Something strange is afoot here."

Do not use aircrack-ng to convert to hashcat formats, because aircrack-ng has several unfixed issues in detection of handshakes:
https://github.com/aircrack-ng/aircrack-ng/issues/2079
https://github.com/aircrack-ng/aircrack-ng/issues/2136
https://github.com/aircrack-ng/aircrack-ng/issues/1993

I suggest to convert to hashmode 22000 format (no longer binary format like deprecated hccapx format).
In addition to that, I suggest to use the PMKID:
https://hashcat.net/forum/thread-7717.html

Most of TALKTALK routers transmit a PMKID:
https://wpa-sec.stanev.org/?search=TALKTALK

example (PMKID in hashmode 22000) from:
https://hashcat.net/wiki/doku.php?id=example_hashes

Code:
$ hashcat -m 22000 WPA*01*4d4fe7aac3a2cecab195321ceb99a7d0*fc690c158264*f4747f87f9f4*686173686361742d6573736964*** -a 3 'hashcat!'

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework

Have given it a go on the website using that to convert the cap to hccapx and still the same issue, also tried hcxtools to convert the cap and still the same issue.

I will give HCXDumpTool a go in a bit and see if that makes any difference. 

It's very strange that it works fine on my Windows setup (well did till the GPU gave out), but refuses to work on a cloud setup.

I will have another play, I have a few routers hanging around to test things out on.

Strangely this TalkTalk router doesn't ever seem to generate any PMKIDs, why that is I am unsure.
