I backup recently, I want to restore from my backup ,but when I go to ā€œRestore & Replaceā€ > the imfomation was show below:
Important: To restore, pick the parent folder of ā€˜/backupā€™

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 Iā€™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 ā†µ

telnet to test connection is ok

telnet 127.0.0.1 11922                                                                                        35 ā†µ

I donā€™t know the root cause is, maybe localhost ssl issue?
