api request times out or errors every time

i am trying to retrieve a formatted list of all items in a group collection (~500 items) via the zotero api with https://api.zotero.org/groups/xxxxxxx/items/?itemType=-attachment&include=bib&limit=25&linkwrap=1&sort=title&style=apa and then using the Link rel=next response header to retrieve the next pages.

however, every time i try i am getting either a time out or a 500 internal server error response after the first few (~5) pages. what am i doing wrong here?
