curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

[serapath]

just installed it and made a file server.js

const AutoEncryptLocalhost = require('@small-tech/auto-encrypt-localhost')
const server = AutoEncryptLocalhost.https.createServer()

it says it's runnig:

   📜    ❨auto-encrypt-localhost❩ Local development TLS certificate exists.
   ✨    ❨auto-encrypt-localhost❩ HTTP server is listening on port 80.
Web server is running at https://localhost
ips [ '127.0.0.1', '192.168.0.13' ]
   👉    ❨auto-encrypt-localhost❩ Redirecting HTTP request to HTTPS.
   👉    ❨auto-encrypt-localhost❩ Redirecting HTTP request to HTTPS.

but opening https://localhost:80 in google chrome gives me:

This site can’t provide a secure connectionlocalhost sent an invalid response.
ERR_SSL_PROTOCOL_ERROR

and using curl https://localhost:80 gives me:

curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

Something seems to not work properly, but I don't have much experience with certificates yet. Any help is appreciated :-)

Here the same with curl and the --verbose flag

I'm running Linu Mint 19.3

when I initially ran the auto-encrypt-localhost server it logged:

   📜    ❨auto-encrypt-localhost❩ Setting up…
   📜    ❨auto-encrypt-localhost❩ Installing certutil dependency (Linux) using apt…

      throw er; // Unhandled 'error' event
      ^

So I followed the README and did sudo sysctl -w net.ipv4.ip_unprivileged_port_start=0 net.ipv4.ip_unprivileged_port_start = 0, after which it ran and logged:

   📜    ❨auto-encrypt-localhost❩ Local development TLS certificate exists.
   ✨    ❨auto-encrypt-localhost❩ HTTP server is listening on port 80.
Web server is running at https://localhost

PROBLEM

• In firefox I get Error code: SSL_ERROR_RX_RECORD_TOO_LONG with auto-encrypt-localhost module.
• running: openssl s_client -connect localhost:80 for auto-encrypt-localhost gives me:

I found another module https://www.npmjs.com/package/https-localhost which seems to do something similar to auto-encrypt-localhost, and when it runs, I can actually navigate to https://localhost and the server responds, but google chrome still tells me the certificate is invalid.

• In firefox I get Error code: SEC_ERROR_BAD_SIGNATURE with that https-localhost module.

[serapath]

Is there a way to:

1. remove the certificate?
2. check the certificate?
3. list all the certificates?

It seems something with the certificate didn't properly work, but I'm not sure how to debug that. I'm happy for any pointers :-)

Hmm, sorry for the hassle. It seems like the initial run permission error might be to blame. I will look into how we can handle that better.

In the meanwhile, can you please try deleting the configuration and trying again? The following should do it:

 rm -rf ~/.small-tech/auto-encrypt-localhost

[serapath]

Oh, didn't notice that it created this in my home folder. I removed it. Sadly, it still didn't solve the issue.

node serve.js

   ✨    ❨auto-encrypt-localhost❩ HTTP server is listening on port 80.
Web server is running at https://localhost

But visiting https://localhost doesn't do anything, but visiting https://localhost:80 at least seems to exist:

• firefox

Secure Connection Failed

An error occurred during a connection to localhost:80.
SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

• google chrome

This site can’t provide a secure connection
localhost sent an invalid response.
ERR_SSL_PROTOCOL_ERROR

For comparision, trying with https://localhost or https://localhost:443 or https://localhost:54321 gives me:

• firefox

Unable to connect
Firefox can’t establish a connection to the server at localhost.

• google chrome

This site can’t be reached
localhost refused to connect.
ERR_CONNECTION_REFUSED

Which at least tells me, both browsers found something and not nothing, but it still doesn't work.

What platform are you testing on? Let me know and I’ll try and reproduce.

[serapath]

Thx :-)

https://github.com/small-tech/auto-encrypt-localhost/issues/3#issuecomment-674605936 is where i mentioned Linux Mint 19.3 (XFCE Desktop) ... I am using my Laptop, which is a HP Spectre x360 15" and i guess it's a 64bit architecture. It's an Intel Core i7.

Did you have any success reproducing it?

[aral]

@serapath Sorry I’ve been so slow on this. I wasn’t able to reproduce it. Wondering if it’s still an issue for you on the latest 7.x line?
