It really depends on time of day, day of week, and your provider as to which one is working the best. If you keep getting error messages the easiest way to find the best API is the peakd benchmark, it is kind of slow, takes about a minute and a half sometimes longer for me, but lets you know the api that is best, and the ones having errors.

Like I said it can be slow at times. Also to avoid any conflicts I always make sure that my hive keychain is set to the same as my peakd one. I am at a total loss however when it comes to using the hive.blog site.
That was very helpful thank you!
