I am having trouble finding out the cause of this problem since I am not able to replicate it, majority of the devices and different internet connections I use have no problem loading my website, but I received a report where a single client was having problems loading the homepage itself, upon checking there have been 74 reports of error 520 in error analysis of cloudflare. The client themselves have already come into contact with their internet provider and said that it was not a problem on their side as it was a server problem with host. I have suggested using mobile data with the same device of the client to see if the website would load and it did.
I am leaning towards the problem being with their internet configuration as I have checked with our hosting provider and there were no problems detected and the client is the only report I have received having this problem, or could this be because I only have a free account in cloudflare?
I have asked the client to run a tracert and send the har file when the loading error occurs. In regards to the tracert it completed its route and doesn’t seem to have a problem, and in the har file I am not sure how to move forward with this information, assuming that this file would be of help in this thread I asked for it.
Any insight would be really helpful and I would appreciate it thanks!
sidenote: I am not familiar with the standard of how to report such issues so bare with me
