I have been struggling with this weird issue. I have created the sitemap of a website. The sitemap is dynamic and has a huge set of URLs.
The problem I'm facing is that google is not accepting it. On deeply investigating I found out that there is some kind of weird hexadecimal code before the 'https://prnt.sc/qkdbhc'
You won't be able to see it while visiting the sitemap link or even viewing the source code. I was able to detect it using the 'https://websniffer.cc/'
I debugged in every way to check if that is coming from my code, but no use. Putting this question here, maybe someone encountered this problem and solved it.
Immediate help would be appreciated.

I'm the creator of the WebSniffer tool that you used to test your sitemap. I'm terribly sorry, but this hexadecimal code is a bug of our sniffer script, which is known and will be fixed soon. It has nothing to do with your sitemap.
I tested your sitemap with the xml-sitemaps site and your sitemap seems to be valid. There is also a Sitemaps testing tool within the Google Search Console. I highly recommend to use it to figure out if and what kind of complains does Google have in regard to your sitemap.
Hope it helps.
Update as of 2024: The aforementioned bug has been fixed.
