Would be nice to choose gateway and region and asn as you are using digital ocean and hetzner with amazon with option to use ip4 or ipv6. Currently many IP that you are using are bad bad on abuseipdb and those who uses it just block it.
Also worth to mention to change HEAD to GET ( allow to choose )
So:
Choose Region USA/EU etc.:
Choose method (GET/HEAD .. etc):
Choose Gateway Region:
Choose ASN for above
Choose ipv4 or ipv6 only
