Bug Description
When trying to enumerate subdomains using the SecurityTrails source for multiple different domains with many subdomains, I get the message "Found 0 subdomains". The issue is only with SecurityTrails because the other sources work(the API key was configured in the config file, and of course, on the SecurityTrails website you can find the subdomains).
In addition, I tried using the Curl method from the API documentation and it worked(I have enough API quotas).

Subfinder version
Version v2.6.0 (latest)

The command I used to reproduce this
subfinder -d tesla.com -s securitytrails
