Cloudflare workers blocked my request

I made an API call to a 3rd party site with cloudflare workers but lately I can’t access the workers page through my server. Why can’t my server access it and always getting a 404 error? Is my server blocked? I know the worker request quota is limited to a maximum of 100k a day but I haven’t used it fully. For your information, I tried using another server to access the worker and it worked normally
