Slow Website Loading & 521 Error Code

I’m currently facing a serious issue with my website; it takes over a minute to load. This prolonged loading time frustrates visitors and likely impacts engagement. Sometimes, the loading time increases to 4 minutes, and after that, a “521 error code” occurs.

I need urgent assistance in identifying and fixing the root cause of this slow performance. I would greatly appreciate your guidance if anyone has expertise in website optimization or troubleshooting slow-loading sites.

What steps can I take to improve loading speed and enhance overall performance? Are there specific tools or techniques you’d recommend for diagnosing and resolving this issue effectively?
