Hello Andy.
Any suggestions on what course of action to pursue? Do you think itâs due to the frequency of requests? Since getting the servers whitelisted feels like a lengthy process, that might not work, we are thinking of trying this again on different servers but we donât want them to get blacklisted too since we donât have an endless supply of servers to test with 
If itâs a frequency issue, what is the time gap between requests that wonât get us blacklisted? Weâve been using a 2-minute gap. if itâs not frequency, what else could be the cause?
Thankful for any assistance you can provideâŠ
