Forge + DigitalOcean + LetsEncrypt Blocking Crawlers

Good Day,

I'm using Forge + DigitalOcean with LetsEncrypt SSL and whenever I test crawling with ScreamingFrog I get connection time out, so I assume something is blocking crawling on the website. What I know:

• I don't have a no robot meta tag.
• The crawler crawls 4 pages only.
• I have redirects from non-https to https, and from non-www to www
• I added asset caching to nginx configuration and that's the only thing that I changed
• It's the same on all my websites that use Forge + DO and LetsEncrypt.
• It's not the case for websites without LetsEncrypt

EDIT: tested the website without the LetsEncrypt certificate and it crawled fine, with LetsEncrypt it blocked crawling

Thanks in advance
