Issue pointing DigitalOcean Droplet server to NameCheap domain

Hello! I am a researcher currently trying to conduct a series of online experiments with JATOS in psychology. Due to the pandemic, my access to participants has been halted, as people can’t come to my lab at the university. So I had to transfer my work online. With minimal programming experience, this has been a very demanding task (obviously). I chose JATOS to bring my studies in the online environment, and they strongly recommended using a cloud-based server, specifically DigitalOcean. Due to severe lack of time, I just blindly followed the instructions they gave out here: http://www.jatos.org/JATOS-on-DigitalOcean.html In order to be able to add encryption with Traefik, I purchased a domain name on NameCheap, psy-research.xyz, and tried to direct the Droplet there, according to the instructions found here: https://www.digitalocean.com/community/tutorials/how-to-point-to-digitalocean-nameservers-from-common-domain-registrars. NameCheap told me it would take up to 48 hours to activate - and 50 hours later, it did not. I am very concerned that I did something wrong in my setup, or that I did not do everything I was supposed to do. My time is very very limited - on Saturday morning, I have to send links to my participants. I would immensely appreciate any help or feedback on whether I did everything right. I will sum up my actions below and add pictures to illustrate: In the section - Create New Record -, I only filled in the A part, where I copy-pasted what I think is the IP of my droplet 159.65.93.60. For hostname, I wrote @, although I’m not sure that’s right. Should I have filled in any info in the other categories (e.g. AAA, CNAME, MX, TXT, SRV etc.)?

In my NameCheap account, I wrote the 3 nameservers (ns1.digitalocean.com, ns2…, ns3…), and checked the green option. That’s all I did there.

I do realize my question is most likely silly. I’m in a strange situation, where I need to abide by a very strict timeline with my research, and it is very important that this works, because it’s too late to try out anything else. I would normally read up on this stuff myself, but I don’t have the time.

Any feedback or help would be immensely appreciated!!
