When trying to connect a new WordPress node to my WordPress website, credentials aren’t saved. It seems that the test n8n does after inserting credential is not going through.
What is the error message (if any)?
No error, just the Save button wheel is spinning since minutes and nothing happens. Tryied multiple times.
I successfully connect through curl, then copy/paste the curl command into the “Import cURL command” field of a HTTP node.
Sadly, also this was a failure. The request didn’t get through using an HTTP node. The request got timed out.
I have just had a quick look and I don’t get any issues when connecting from n8n to a test Wordpress 6.5.2 install using an app password.
It sounds like maybe your n8n instance can’t reach your Wordpress install at all, What happens if you use an http request node and try to get https://volevotutto.it/wp-json/wp/v2/posts without any authentication? For me I get a list of your posts back so it would be interesting to see if you get the same result.
you’re right, it seems n8n isn’t able to reach my website at all.
How could it be possibile?
N8n is installed in a Droplet on Digital Ocean using Docker, alongside with Caddy.
I followed this guide to do this setup: Digital Ocean | n8n Docs
N8n is hosted in a third level domain of my main domain (planbproject.it). I have to notice that:
trying to reach volevotutto.it (different host, different domain) I got timed out
trying to reach planbproject.it (different host, same domain) I got an authentication error, as the n8n’s ip isn’t safe
Any idea on what I should look into to solve this situation? (mainly the one with volevotutto.it)
Also: I checked and the Droplet itself isn’t able to execute a get request with curl, so the problem should be serverside and not from n8n.
So, I fixed the problem (Thanks Jon, your insight pointed me in the right direction)
It was the DigitalOcean IP that was blacklisted globally. (Veru disappointing )
If anyone interested, I will explain below how I did it.
Starting point
I had setup the following:
Droplet with Caddy + N8N containerized in docker (Following this guide: Digital Ocean | n8n Docs)
third level domain directed to the droplet (very important for me to use webhooks and ssl)
Create new droplet
Make a snapshot of the droplet
From the snapshot, select “create new droplet”. This will create a droplet from the snapshot you just created. everything will be the same (N8N, workflows, users, and so on).
From DigitalOcean, delete the domain I created
Create a new (third level) domain and connect it to the new droplet
From where you’re hosting the domain, go and change the dns record accordingly with what DO suggest to do to connect your domain.
Wait for the DNS to be propelry propagated
Enjoy the droplet with clean IP.
In the unfortunate event that the new droplet has a blasklisted IP too, try again, I guess.
