I have a simple error that needs fixed on my php script

I am having an issue with my song request script. This issue is NOT all the time, its only somtimes. So to repeat. SOMETIMES the php script works and lets the user submit a song request, and sometimes it doesnt. The error message is below. I dont want you to "try" to figure it out. I want someone that KNOWS exactly what the problem is and can start there. The script searches my hard drive for music and then shows it to the user. The user can then select the song they want to hear on the live broadcast radio station and it puts it in cue. This php script interacts with other proprietary software on my machine. You must have knowledge with PHP, SQL, and an extensive Networking background. Due to the nature of whats involved, i will NOT provide unmonitored access. You will tell me what to try, or what to change and i will make the changes OR we can do a team viewer session. No credentials will be provided to you. Error message: ERROR 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
