Timeout issue for subscribing large ics calendars

[mkrecek234]

Steps to reproduce

1. Subscribe a calendar invitation which is large (2 MB) - "Neues Abonnement aus Link" / New subscription from link

Expected behavior

All calendar entries are imported and shown

Actual behaviour

The calendar is shown on the left side, but not a single event is imported. The Nextcloud log says GuzzleHTTP Client timeout 30001 seconds. On the calendar server providing the ics file I cannot see any error - I also can easily download the 2 MB file from that server and import it.

The URL times out for me as well.

[mkrecek234]

@ChristophWurst The URL in my log is sanitized. In the real URL I can easily download this via HTTP without issues. Or do you mean you can replicate the issue also with another (your) URL?

[ChristophWurst]

I used the URL from your log

[tcitworld]

Operation timed out after 30000 milliseconds with 0 bytes received

Shouldn't it have received at least a few bytes ? Does it work if you try to download the file from the same machine with the curl binary ? Then try with the same Accept headers and user-agent.

[mkrecek234]

Agree this looks strange - I also posted an issue with SoGO where I try to subscribe the calendar from.

Hi!

Just got the same, tried to subscribe to a google cal that weight 1.9MB. Importing it in Thunderbird takes around 15s. In Nc, it times out after 60s, but if I come back after some minutes, I can see the cal in the web interface.
