We're aware of issues with EngX not loading properly or taking a long time to load. We have seen:
- captcha forms asking if we're human
- 504 gateway time out errors
- Error 15 access denied
Please let me know if you're seeing anything different to what's been said above.
We have reported the issues and they are being investigated. I'll give more updates when I receive them.
Sorry for any inconvenience
