2022-10-19 https://mygmrs.com and https://mygmrs.network offline?

 

Blank pages displayed for both.  Some data is displayed in the "View Page Source", seems like backend services may be offline?

Can our admin team provide some feedback on coming back online?  I can donate a few hours to helping bring us back online if needed.  Thanks for keeping a great site operational thus far.

Hope all is well!

Thanks for the prompt reply.  We're located in the Seattle Washington Area.

 

This is interesting, and I'm going write it up to the web browser.  One instance of firefox gives me this page:

<!DOCTYPE html><html lang=en><head><meta charset=utf-8><meta http-equiv=X-UA-Compatible content="IE=edge"><meta name=viewport content="width=device-width,initial-scale=1"><link rel=icon href=/favicon.ico><title>myGMRS.com Network</title><link rel=stylesheet href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900"><link rel=stylesheet href=https://cdn.jsdelivr.net/npm/@mdi/font@latest/css/materialdesignicons.min.css><link rel=stylesheet href=https://api.mapbox.com/mapbox-gl-js/v1.11.1/mapbox-gl.css><link href=/css/about.572b7a25.css rel=prefetch><link href=/css/manage.2e69c63e.css rel=prefetch><link href=/css/map.b83ec1be.css rel=prefetch><link href=/js/about.763f6381.js rel=prefetch><link href=/js/chunk-2d22497b.10c313fd.js rel=prefetch><link href=/js/manage.a23b813d.js rel=prefetch><link href=/js/map.40493aa4.js rel=prefetch><link href=/js/setup.c0645d7b.js rel=prefetch><link href=/css/app.e2e9493c.css rel=preload as=style><link href=/css/chunk-vendors.d274a882.css rel=preload as=style><link href=/js/app.ebd81a6b.js rel=preload as=script><link href=/js/chunk-vendors.47017c54.js rel=preload as=script><link href=/css/chunk-vendors.d274a882.css rel=stylesheet><link href=/css/app.e2e9493c.css rel=stylesheet></head><body><noscript><strong>We're sorry but myGMRS.com Network doesn't work properly without JavaScript enabled.

The other instance gives me the expected and usual mapping for https://mygmrs.com/ and https://mygmrs.network/ .

Note: Javascript is not disabled in that particular browser.

The same instance which is generating the errors is rendering this forum without issues.

 

(Firefox version 105.0.3 (64-bit) // MacOS 12.6)

Thanks for the prompt reply!

Please disregard the post and thanks everyone for keeping a great site up and running.

The problem turns out to be a setting on the user side, the site is running well.

 

 

TL;DR

There is  javascript check built into the mygrms.com site.  One of the checks it seems to do for javascript is to use WebRTC. ( https://webrtc.org/ and https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API  are provided for further reading. )

There exists a way using WebRTC to show the IP address of the local computer running the web browser on the local network accessing the page.  In Cisco Systems nomenclature this might be termed the computers inside IP address.  This is the address of a computer which the wifi router sees on most networks and is of limited use outside of the the network after the address has been translated to a global outside IP address.  In some social and professional circles exposing this IP address is deemed to be sharing unnecessary information with external sites.  In some development circles, a developer may wish to test an application with WebRTC both enabled and disabled. 

In my case, the browser(s) in use had Javascript enabled, but WebRTC disabled (there's tools to do that, there might be advanced config settings in modern browsers to toggle too if intersted.)

Most sites, including the Facebooks, Apple/Amazon, Netflix, Google, Microsoft, etc. will still render a page with WebRTC disabled.  The Invision Community and by extension https://www.mygmrs.com/ seem to use the WebRTC feature (check out the above link from mozilla WebRTC_API) to determine if Javascript is running. 

It seems in this case disabling WebRTC causes this site to indicate it cannot be displayed becuase Javascript is disabled.  The page source is posted above, but the readable page appears blank to a user when WebRTC is disabled.  Looking at the page source from above,

<!DOCTYPE html><html lang=en><head><meta charset=utf-8><meta http-equiv=X-UA-Compatible content="IE=edge"><meta name=viewport content="width=device-width,initial-scale=1"><link rel=icon href=/favicon.ico><title>myGMRS.com Network</title><link rel=stylesheet href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900"><link rel=stylesheet href=https://cdn.jsdelivr.net/npm/@mdi/font@latest/css/materialdesignicons.min.css><link rel=stylesheet href=https://api.mapbox.com/mapbox-gl-js/v1.11.1/mapbox-gl.css><link href=/css/about.572b7a25.css rel=prefetch><link href=/css/manage.2e69c63e.css rel=prefetch><link href=/css/map.b83ec1be.css rel=prefetch><link href=/js/about.763f6381.js rel=prefetch><link href=/js/chunk-2d22497b.10c313fd.js rel=prefetch><link href=/js/manage.a23b813d.js rel=prefetch><link href=/js/map.40493aa4.js rel=prefetch><link href=/js/setup.c0645d7b.js rel=prefetch><link href=/css/app.e2e9493c.css rel=preload as=style><link href=/css/chunk-vendors.d274a882.css rel=preload as=style><link href=/js/app.ebd81a6b.js rel=preload as=script><link href=/js/chunk-vendors.47017c54.js rel=preload as=script><link href=/css/chunk-vendors.d274a882.css rel=stylesheet><link href=/css/app.e2e9493c.css rel=stylesheet></head><body><noscript><strong>We're sorry but myGMRS.com Network doesn't work properly without JavaScript enabled.

The content expected to be displayed is: "We're sorry but myGMRS.com Network doesn't work properly without JavaScript enabled. Please enable it to continue."

Most modern browsers have Javascript enabled by default; I don't expect this to be an issue for the larger mygmrs.com community except for the TL;DR described herein.  I'd like to keep the discussions to the radios and GMRS and our community, but if you're wondering why in some obscure case the mygmrs.com site didn't render, here it is. :)

Thanks all for the prompt replies and I'm happy to report the mygmrs.com site is rendering well today (with WebRTC setting turned off of course).
