unable to regenerate thumbnails

[Moderator note: Please don’t capitalize your titles]
Hello recently i changed domain in my webhost, it used to be xxxxx.comeze.com and now i have changed it to the URL of my offical Domain name obtained in Namecheap.

i had many issues with this change starting from the Database, i was unable to enter to wp-admin of my website to manage it by all those issues i have figured it out already what i cannot fix so far (i’ve been reading and trying different pluging for this for 2 days) is that thumbnails don’t show up.

Here is how it looks:

And here you will see that if i click on any of the thumbnails the complete image shows up as expected:

I for the life of me cannot get this fixed so i am asking for help

Thanks in advance,
