Trouble with emails, errors with [websocket ]and /cable

Oops. Forgot to include the ENV file:

Here it is: https://pastebin.pl/view/8180aad9

Hi @Fabio dos Santos, have you tried using something like Swaks to confirm your SMTP settings? That can offer insight into the correct ENV config.

I'll have a think about how we can make this easier, it's nothing we at Loomio have written, I'm not sure why it seems so many people have trouble configuring Loomio/Rails to send mail.

Hi .

Thanks you so much for your response!I have been looking into this.

It seems like a conection error, and someone pointed how they needed to configure the Proxy correctly. So yesterday night, I looked into the jwilder/nginx page on Docker Hub. This particular bit of info from https://hub.docker.com/r/jwilder/nginx-proxy/ called my attention:

+++++++++++++++++++++++

Internet vs. Local Network Access

If you allow traffic from the public internet to access your nginx-proxy container, you may want to restrict some containers to the internal network only, so they cannot be accessed from the public internet. On containers that should be restricted to the internal network, you should set the environment variable NETWORK_ACCESS=internal. By default, the internal network is defined as 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16. To change the list of networks considered internal, mount a file on the nginx-proxy at /etc/nginx/network_internal.conf with these contents, edited to suit your needs:

# These networks are considered "internal"
allow 127.0.0.0/8;
allow 10.0.0.0/8;
allow 192.168.0.0/16;
allow 172.16.0.0/12;

# Traffic from all other networks will be rejected
deny all;

When internal-only access is enabled, external clients with be denied with an HTTP 403 Forbidden

+++++++++++++++++++

My email server is not a container or even within the local network. I will try this as soon as I can. But maybe this is the answer: the "external" are not being accessed. That would explain the errors with the email setup.

I'm kind of new to this docker things. I think is amazing. I'm assuming that I need to create /etc/nginx/network_internal.conf with the appropriate IP numbers. If not, please let me know!

I can't tell you how grateful I am, for the software, and for the response. Thank you!

I created the file mentioned above, but no change.

Another thing that caught my eye was the SSL Backends config in NGINX. It could well be that it is trying to access website with HTTP, and the server does not authenticate because it should only contact through HTTPS, or port 443. I have just tried to add this to the env to see if it works.

VIRTUAL_PROTO=https
VIRTUAL_PORT=443

OK! Some adicional information (I've tried some things.)

Cable/Websocket errors:
Persist when I add the email server's IP address to etc/nginx/network_internal.conf

Cable/ Websocket cease:
When I add the SSL Config to the ENV. HOWEVER, then I have authentication problem to load the website.

Here is the error:

'loomio-nginx   | nginx.1    | 2020/04/22 13:34:04 [error] 85#85: *1 SSLdohandshake() failed (SSL: error:1408F10B:SSL routines:ssl3getrecord:wrong version number) while SSL handshaking to upstream, client: 177.194.12.130, server: loomio.associacaomusicalsuzuki.com.br, request: "GET / HTTP/2.0", upstream: "https://172.17.0.5:3000/", host: "loomio.associacaomusicalsuzuki.com.br"

In both cases, I still get this warning about loomio-mailin: Not sure if this is relevant.

loomio-mailin  | warn: Webhook http://app:3000/email_processor/ seems invalid or down. You may want to double check the webhook url.

There seems to be some conection with nginx-proxy, and its connections to the internet, and the containers, and it is does not seem to be a problem specific to the code-base, but rather in configs.

Thanks!

Are you trying to solve SMTP or Cable issues?

I think you should ignore the cable issues and focus on SMTP, the cable stuff is something that should just work given the config I've provided, and if not, I'll look into it. It works fine for the Loomio installs I support, but I'll review it.

SMTP is critical though, and I think you should confirm your SMTP config with swaks, then report back if loomio works or does not work with that config.

Good morning!

Sorry. I was not aware that they were different issues!

I got the email server to work with Swaks. I have received the email.

./swaks [email protected] --from "[email protected]" --auth LOGIN --auth-user "[email protected]"  --auth-password "RANDOMPASSWORD" --server mail.associacaomusicalsuzuki.com.br -tls

And the output:

Will try to set this up on Loomio now.

Tried to following configuration, but still get a "fail" message for the email.
Here is what is in my env

# smtp settings

[email protected]

SMTP_AUTH=login

SMTP_DOMAIN=associacaomusicalsuzuki.com.br

SMTP_SERVER=mail.associacaomusicalsuzuki.com.br

SMTP_PORT=465

[email protected]

SMTP_PASSWORD=RANDOMPASSWORD

SMTP_USE_SSL=1

REPLY_HOSTNAME=associacaomusicalsuzuki.com.br

# helper bot is the account which welcomes people to their groups.

[email protected]

RAILS_ENV=production

I changed SMTP_AUTH to login.

I feel like that only information that is actually missing (when in compared to SWAKS) is TLS, which I don't know how to add to the env.

Here is the error log:
