Hello,

There is no CNAME for that domain -

https://www.nslookup.io/domains/blogram.com.tr/dns-records/#google

sorry I am new on that , I have a domain 'blogram.com.tr' and I added it with custom domain button and I set port 8080, did I do it wrong ?

after that it looks like this and I used that infos to create new cname

can you explain me what I should do step by step

www.blogram.com.tr works fine now, I can see your site.
