I've lost access to the Web UI and API monitoring as well. I was upgraded to 1.20 a week and a half ago and had to change to https to get the access. Then a few days later, I could no longer get web access from my notebook, but could from another PC on my network. At that stage, the API access from a Unix box was still working and feeding into my Home Assistant setup. Then everything stopped working. It looks like all web access has been disabled, including through the Powerwall's own access point. I talked to Powerwall support and they confirmed that turning off the Web and API access is separate from the 1.20 upgrade, but needs the 1.20 for them to be able to do it. In other words, just the upgrade to 1.20 won't turn off Web access by itself, but allows Tesla to remotely turn it off after it has been upgraded.
So, my suggestion to anyone who continues to want the Web and API access would be to remove the SIM card from the gateway and block remote access to the Powerwall at your firewall so Tesla can't disable it. If I'd known this was coming, it's what I would have done. I've made my displeasure known to Tesla and have told them I require it to be turned back on. I've also pointed out to them that Consumer Affairs laws in Australia don't allow companies to remove functionality from a product after you have paid for it. I'm giving them 2 weeks to sort it out, them I'm taking them to my state Consumer Affairs Tribunal. They need to realise they don't own the Powerwall, I do.
