I’m follow the Tutorials to set backup
Backup to Google Drive or locally to any cloud provider

I backup recently, I want to restore from my backup ,but when I go to “Restore & Replace” > the imfomation was show below:
Important: To restore, pick the parent folder of ‘/backup’

To your local hard drive

and the alert continue to showing that I need to download memex-backup-helper,but I already download and install before

so I reinstall chrome extension, reinstall memex-backup-helper, problem still occurred.

I open the browser DevTool ,there show lots of errors, I notice when I click I’m Ready button, an error log showing

options.js:1266 GET https://localhost:11922/status net::ERR_SSL_PROTOCOL_ERROR

than I use curl tool to try ssl issue , the log showing below

curl https://localhost:11922/status  -vvv -kvL                                                                 1 ↵

telnet to test connection is ok

telnet 11922                                                                                        35 ↵

I don’t know the root cause is, maybe localhost ssl issue?
