WebSocket connection to 'wss://site1.local/socket.io' failed: Error in connection establishment: net::ERR_NAME_NOT_RESOLVED

yashodhan · May 20, 2019, 9:39pm

I ran into following issue, soon after fresh install on Ubuntu 18.04 LTS Cloud server with V11 stable branch of Frappe/ERPNext.
Installation completed without any issues, but during setup wizard itself, while uploading logo errors were visible inside browser console.

WebSocket connection to 'wss://crm.site.ext/socket.io/?EIO=3&transport=websocket&sid=lLRcThF1iZ4deOzLAAAB' failed: Error in connection establishment: net::ERR_NAME_NOT_RESOLVED

I had SSL installed and ERPNext site was created with same name as domain itself. (crm.site.ext)

Update #1: This turned out to be OS Configuration issue, not directly related to Frappe/ERPNext.
Update #2: Unfortunately problem returned after sometime.

Solution

Important Files to check

1. /etc/hosts
2. /etc/resolv.conf

When I provisioned server, my server hostname (ex. erp.site.ext) was added with localhost ip address in /etc/hosts file instead of my Public IP automagically. Resulting into scripts failing to resolve actual public ip address of my hostname.

So, Make sure to set your Public IP followed by hostname for direct resolution inside /etc/hosts
Example:

127.0.0.1    localhost
4X.XX.2X.XXX    erp.site.ext

# The following lines are desirable for IPv6 capable hosts
::1          localhost ip6-localhost ip6-loopback
ff02::1      ip6-allnodes
ff02::2      ip6-allrouters
X00X:1XfX:X:2XXX:XXX0:0XXf:XeX9:XX9X            erp.site.ext

Similarly, also make sure to add A for IPv4 & AAAA for IPv6 for hostname you are trying to use with Frappe/ERPNext. Test this hostname is correctly resolving configured public ip address of your server where Frappe/ERPNext is installed using https://mxtoolbox.com or command: dig +short a erp.site.ext

In case of /etc/resolv.conf, make sure to use responsive nameserver such as google public dns.
Example:

/etc/resolv.conf
nameserver 8.8.4.4
nameserver 8.8.8.8
nameserver 127.0.0.53
options edns0

~~After this exercise, all my error notifications inside browsers console gone and ERPNext working just fine as it always does!~~

Similar issue from old thread (tried out but issue persists)

ashish-greycube · May 21, 2019, 10:15am

[a]On bench restart if you are seeing error on console that socketio restart not successful. In that case try following
$ bench setup socketio
[b]Try to run site in production mode. i.e. in site_config.json remove “developer_mode”:1 entry

yashodhan · May 21, 2019, 12:48pm

Thanks for reply, I have tried it without any luck.

ashish-greycube · May 22, 2019, 3:48am

There could be 2 possibilities
[a] image issue due to SSL
Try : remove https and make site simple http
On side note for me, running

$ sudo apt install libssl1.0-dev

had solved the issue
[b] image issue due to file I/O permission etc
Try : Give some http image URL from web, instead of upload image

yashodhan · May 24, 2019, 6:30am

Thank you so much for your help and feedback.

My findings are none of above worked to solve the issue.
Because recently I have installed ERPNext on fresh server using bench easy install method.
Kept everything to default such as site1.local (automatically created during install) and accessing ERPNext directly from Public IP. No SSL, Custom domain etc.

Even in that case my console is filled with errors immediately after setup wizard.
