Lower limit of the "php max execution time" in a shared hosting environment

Hi there,

IĀ“m trying to use nextcloud in a shared hosting environment.
My contract specifies the ā€œphp max execution timeā€ with 60s
Uploads above a certain size will fail and I came to realize that itĀ“s probably Uploads that take more than 60s.
Is there any way to investigate this further?
And if itĀ“s really the cause any solution? Lowering the uploaded chunks?

Since installing nextcloud from scratch I donĀ“t get any messages in the log. Before there where different messages but I didnĀ“t save them.

Thanks,

Nils
