Having an issue with many https sites not loading, but the easiest to replicate seems to be assets off https://yescrowd.optus.com.au/.
The yescrowd site itself works but when using the internet through an optus home wireless router assets from / don't load.
* multiple browsers - reset settings and clear all data
* multiple wireless router devices, ac800s & e5186
* both devices firmware are up too date and factory reset multiple times
* all forms of connection, being usb, ethernet and wifi
* multiple sims/accounts (a family members)
* multiple client devices, including windows 10, linux and android
* multiple internet connections, all work correctly to get assets from the site except when using the optus home wireless product, like iinet, telstra, aws, using a command line curl -vo/dev/null '/html/assets/icomoon.ttf' for standardized testing.
* tried multiple sites and as a result different cell tower id's (went driving) to validate it's not localized to a specific tower (we at least towers in my area hurstville).
* with wireshark I can see the issues due to a failure to negotiate during tls negotiations (tried all versions of tls), with the response packets (which are 1508 bytes) aren't being returned and the client keeps resending the same request packet over and over.
* clamping the clients mtu out the interface, including modifying the mss size on the tcp headers all the way down to 1400 from the typical 1460.
The majority of https sites work, but many don't.
I can't confirm if the problems always been happening as I didn't exactly notice 100% what was going on for awhile.
But I would say it's been happening for the past week at least.
Any thoughts on what could be causing this or what to do next to resolve it ?
Solved! Solved: Go to Solution.
the hostname that was filtered out of my previous message was assets from optus.i.lithium.com fail to load when using https.
Just to let everyone know, if your having this issue contact optus support.
They made a "change" and after a factory reset my service is now working 100% with all https sites.
When using my Huawei B525 I am unable to access yescrowd.optus.com.au and the My Account login page.
If I move my SIM into a Huawei E5577F (mobile hotspot) then everything works but much slower
I presume this is something that will have to be resolved by tech support on my account but worth asking here if anyone knows any trick to get it to work
A couple of people have posted about this issue in the last few months:
When chatting with Technical Support if they get a bit stuck I would refer them to these threads. It sounds like a HLR rebuild is the way to go?
We would really appreciate it if you returned to Yes Crowd to let us know if you got it resolved. If not, we'll try something different.
Thanks for the related issues.
I have now had 2 chats with online support about the issue but it has not yet been resolved.
An escalation has been made and I now have a ticket number.
To me it looks like a TLS handshake issue during the connect being caused by the NAT with the B525 modem but I may be completely wrong as that would require a firmware update
Thanks for the update, some progress made getting a fault ticket looked at.
If it hasn't progressed by the start of next week, please let me know what the ticket number is and I'll follow up.
Hello Iain and Ray,
Back on 8th December when I started this thread,
I was unaware of a few other people, like you, with the same problem. Have you had any success since 11th December?
I am still unresolved, technical support was no help, nor interested "aw, haven't heard of that problem before, have you reset your modem" is about as far as I could get. Online Community Manager Dan_C tried to help, but didn't get anywhere.
And now that I have disconnected my Telstra ADSL service, the only way to access my Optus account and Yes Crowd (like this reply) with a device running OSX, is to hotspot a phone.
It is a pity that Optus technical support doesn't want to follow through on stuff. The too hard basket is the easier option.
