Stuck on loading data on login page

Hi.
I got home from work today and my hassio installation on an RPI3 doesn’t work anymore. I am stuck on the login screen displaying “Loading data”. The “Loading data” screen comes up when trying to access hassio using my private DNS. When I try hassio.local:8123 nothing shows up. I tried uncommenting almost my entire configuration.yaml to no avail. I also did a fresh install and restored from a fully working snapshot. After the restore, the problem returned. I have also tried removing various files in the .storage directory, but this also doesn’t work. I have no idea what more I could do.
I also tried different browsers if cache was a problem, but no solution here. I have looked at other threads with similar issues, but none of the solutions have worked for me.

My log is pasted below. It seems there may be a problem with my tellduslive configuration. I have added this using the Components page on hassio, so do not know how I can remove it without accessing the GUI, nor do I know if it is tellduslive that is actually causing the problem.

Actually, the loading data page also comes up after I have unplugged my RPI, so it seems that I can’t access hassio at all. I can, however, access the Samba share I’ve set up.

Hassio suddenly started working again after being shut down last night. Have no idea what happened, but atleast it is working.

im currently facing this issue,

on the logs i see this as the last line about pychromecast , like you i am able to access the samba share.

2019-01-28 23:46:07 ERROR (SyncWorker_1) [pychromecast.socket_client] Failed to connect, retrying in 5.0s

Found a solution for this, rather a workaround

if you have ssh access or samba goto /config/.storage/ dir and delete chromecast part in core.config_entries

nano /config/.storage/core.config_entries
